UPath kwargs are not persisted from layout root to BIDSFiles

[effigies]

The sqlalchemy serialize/deserialize loop makes it nontrivial to keep track of keyword arguments. For example:

from upath import UPath
from bids.layout import BIDSLayout

ds_root = UPath("s3://openneuro.org/ds000102", anon=True)
layout = BIDSLayout(ds_root)

description = layout.get(suffix='description', extension='.json')[0]
assert description._path.storage_options == ds_root.storage_options  # boom

Consequently, anonymous access to S3 datasets is not currently possible, and presumably there are other impacts on other protocols. This should be fixed.

Some previous notes from #1094:

If universal_pathlib provides an API to access these additional parameters, we could consider adding a column to the BIDSFile model and use it while reconstructing. Another approach could be to mutate BIDSFiles after creation, provided the access happens through a BIDSLayout method call that has access to ._root. Alternately, if we could somehow put this information in the SQLAlchemy session, then the BIDSFile.path property could access it on demand.
