- created new module for API model types `eark_validator.model` that contains types for:
  - `Level` (requirements level);
  - `PackageDetails`;
  - `Severity` (of test result);
  - `StructResults` (for structural validation results);
  - `StructStatus` (for structural validation status);
  - `TestResult` (for validation test results); and
  - `ValidationReport` (for final validation report);
- refactored structural validation to use new types;
- small fix to schematron test for `CSIP11` in `mets_metsHdr_rules.xml`;
- new `eark_validator.packages` module for package validation;
- introduced a `PackageHandler` type to start abstraction of package parsing (replaces `STRUCT.ArchivePackageHandler`);
- introduced a `ValidationReport` type to handle final aggregation of validation results;
- added missing `__init__.py` files with appropriate commenting;
- removed some defunct types;
- removed unused imports;
- introduced light use of pydantic, better use to come; and
- unit test improvements and fixes.

FIX: Pylint errors.

- converted struct types to Pydantic; and
- fixed constructors where necessary.

- let the validator handle package unpacking;
- added empty list default for `Checksum`; and
- replaced `pprint` with `print` for now.

- added model types for Checkums and ChecksumAlg types;
- removed/refactored defunct Checksum types; and
- refactored tests to use new Checksum types.

- refactored model code to group related types in modules;
- better inclusing of model code in `__init__.py`;
- completed addition of type hints to methods;
- output of CLI now mostly JSON;
- terminate processing of bad input files quickly; and
- removed unused imports.

- fixed use of `to_upper` and use of `model_validate()` to force upper case checksum values;
- catch `str` initialization of `Checksummer` so that a valid `ChecksumAlg` is always used; and
- added test for case insensitivity of checksum values.

… the deprecated CSIP86 requirement. Replaced with text from CSIP88.

…ead of schemas

…contexts

- `eark_validator/cli/app.py`:
  - validation now uses `eark_validator.model.ValidationReport` module;
  - improved `argparse` docs a little;
  - updated epilog date;

  - `FileItem` and `Manifest` types moved to appropriate `model` modules;
  - `ManifestEntries` and `Manifests` classes now hold API/factory methods for above;
  - no more `Checksum`s from METS files;
  - uses `Path` rather than `str` for file paths;
- `eark_validator/mets.py b/eark_validator/mets.py`:
  - METS validation moved to `MetsFiles` class;
  - use `FileItem` rather than `FileEntry` types for file lists;
  - utility methods for `FileEntry` added;
- added file headers where missing;
- added a `SchematronRuleset.get_reports()` genrator method;

- better/refactored tests; and
- fixed imports post-refactoring.

CI: Python build matrix, 3.9 to 3.12

- added `pickle` based serialisation and deserialisation for `Manifest` class;
- manifests can now be validated against an alternative root;
- fixed faulty `|` as `or` in `MetsFiles.from_file()` method;
- model `MetsFile.default_ns` is now a dictionary of namespace prefixes and URIs;
- fixed handling of relative paths during Manifest creation/validation;
- improved testing of manifest classes; and
- typehints here and there.

- loose model types for InformationPackages, plus removed defunct types;
- JSON output from Pydantic types;
- changed application name from `ip-check` to `eark-validator`;
- streamline application/project versioning;

Including profiles/*.xml and schema/*.xsd in build

…ion-message

Fix/csip88 deprecated assertion message

MAINT: Removed Python 3.9 build.

FEAT: Pydantic types

Done better in project.toml by @dockmd

MAINT: Quick package publication

- fixed the METS example to add `<fptr>` links to the schema and documentation divs; and
- fixed test as example now generates more warnings.

Fix/struct map context fix

- created specification model types;
- removed redundant specifcation types;
- fixed tests;
- removed redundant `__version__` attribute from base module; and
- updated EPILOG date to 2024.

REFACT: Specification types

- cleaned up `StructuralRequirements` some;
- fixed broken property getters in `EarkSpecifications`;
- better tests for specifications and requirements;
- made generators from `SchematronRuleset` properties; and
- prettier printing from the CLI using `rich`.

…dator into refact/rulesets

FIX: Missing XML files

- added case by case tests and data for structural conditions;
- fixed bugs in the structure checking code based on results of the above; and
- added test data for the above.

REFACT: Cleanup rulesets and requirements.

MAINT: Structure rules test coverage

- no functional changes;
- used of `f''` string rather than `str.format()`;
- better used of constants for strings, though not perfect;
- better code documentation, though far from perfect;
- test adjustments to match, though no pylint on test code;
- use of generation expressions rather than list comprehensions; and
- various occurrences of minor issues:
  - unused variables/parameters/imports;
  - overlong lines; and
  - redundant braces and else statements.

MAINT: Address Pylint issues

- removed `StructuralRequirment` class so there is now only a singe `Requirement` class;
- disabled the few legitimate pylint exceptions;
- `ValueError` rather than `None` return for `ChecksumAlg.from_string()`; and
- refactored model string constants to a single `model.constants` module.
