address challenges encountered in implementing the QC test on the data arrays

[leilabbb]

This issue was created based on findings from working on #277

The QC process needs additional conditional statements to handle special cases of data arrays. The following have been already identified and are being tested:

Test 1:
Check the time array for data start time inconsistent with the deployment start time, invalid timestamps, duplicate timestamps, and non-ascending timestamps
Action 1:
The QC tests are skipped and the Global attribute dac_qc_comment is annotated with test 1 results.

Test 2:
Check the legacy variable for an empty array, an array with all fill values, or nans
Action 2:
The QC tests are skipped and the Global attribute dac_qc_comment is annotated with test 2 results.

Test 3:
Check the legacy variables' standard names for non-CF compliant names
Action 3:
The QC tests are skipped and the Global attribute dac_qc_comment is annotated with test 3 results.

Test 4:
Check the legacy variables for the missing attribute "ancillary_variables"
Action 4:
The QC tests are not skipped and the "ancillary_variables" is created

Test 5:
Check variables sharing the same standard name as the legacy variables
Action 5:
The QC tests are skipped and the Global attribute dac_qc_comment is annotated with test 5 results.

Remark: Need a consistent way to parse the deployment start time to complete test 1.
Parsing the deployment name using the specified date/time convention (YYYYmmddTHHMM) defined in the deployment registration guideline.

The following tests have been completed:

• [ x] Test 1: Check the time array
• [ x] Test 2: Check the legacy variables
• [ x] Test 3: Check the attribute "standard_name"
• [ x] Test 4: Check the attribute "ancillary_variables"
• [x ] Test 5: Check shared "standard_name" attributes

The following test need to be added:

• Test 6:

Include non-zero timestamps that are invalid in the timestamps check.
Action 1:
The QC tests are skipped and the Global attribute dac_qc_comment is annotated with test 6 results.

@leilabbb will verify the last test
