"""Convert an abstract CRDS reference file URI into an absolute path for the
file as located in the CRDS cache.
Parameters
----------
reference_uri : string identifying an abstract CRDS reference file,
.e.g. 'crds://jwst_miri_flat_0177.fits'
observatory : string naming the telescope/project for CRDS, e.g. 'jwst'
`observatory` should be omitted, None, or defined as a literal string value.
Omission and the value None are interpreted as 'jwst'.
Returns
-------
reference_path : absolute file path to reference_uri in the CRDS cache,
.e.g. '/grp/crds/cache/references/jwst/jwst_miri_flat_0177.fits'
Standard CRDS cache paths are typically defined relative to the CRDS_PATH
environment variable. See https://jwst-crds.stsci.edu guide and top level
page for more info on configuring CRDS.
The default CRDS_PATH value is /grp/crds/cache, currently on the Central Store.
