Lsstdesc-gcr-catalogs

This release (v0.17.0) contains many under-the-hood changes, in particular, the physical location of all catalog files have been updated (thanks for the help from JoanneBogart heather999).

New feature
- New options `name_startswith` and `name_contains` in `GCRCatalogs.get_available_catalogs`. For example, one can now run:

python
GCRCatalogs.get_available_catalogs(names_only=True, name_contains="object")


to get all the catalog names that contain "object".

New Catalogs
- `buzzard_v2.0.0_4` : another realization of Buzzard 2.0 (thanks to j-dr)

Catalog changes (breaking backward compatibility):
- `baseDC2_5000` has been renamed to `base5000`
- `hsc-pdr1-xmm` has been removed.

This release will be installed on DESC environments on NERSC shortly (thanks for heather999). Please report any issues/bugs by [opening an issue here](https://github.com/lsstdesc/gcr-catalogs/issues).

New catalogs were added in this release (v0.16.1):

- `dc2_object_run2.2i_dr3_with_photoz`: A composite static object catalog that includes the photo-z add-on (thanks to sschmidt23; [see documentation here](https://confluence.slac.stanford.edu/x/uwUwE) (link for DESC members only)).
- `baseDC2_5000_v1.1.1`: (not intended for general use) base catalog for the upcoming sky catalog 5000 (thanks to evevkovacs)

This new release contains no user-facing changes.

For developers

A major change in how catalog paths are specified in the yaml config files is introduced in this version. In particular, all paths should now start with `^/` to indicate that they are stored under a specific root directory on NERSC. This change allows the actual path to be automatically resolved when a user loads the catalogs on different servers.

Thanks to JoanneBogart for implement this change (416).

This v0.15.0 release contains several new catalogs and minor improvements. Most notably, the object catalog and metacal catalog for DC2 Run 2.2i DR3 are now available. You are all encouraged to try them out!

New catalogs:
DC2 Object/Metacal for Run 2.2i DR3
_Thanks for the DC2 Team, and particularly joachimi and EiffL for helping deliver these catalogs to GCRCatalogs_
- Object catalog: `dc2_object_run2.2i_dr3` (and a single-tract version for testing purpose: `dc2_object_run2.2i_dr3_tract3830`)
- Object catalog with metacal: `dc2_object_run2.2i_dr3_with_metacal` (_Note that this composite catalog has 6 fewer tracts than `dc2_object_run2.2i_dr3` due to missing metacal data; they will be supplied in a later release._)

This release contains several new catalogs:

- Photo-z related (thanks to sschmidt23):
- `cosmoDC2_v1.1.4_image_photoz_magerr_10y_PDFcat`
- `photoz_magerr_10y_estimate_image`
- `photoz_magerr_10y_with_pdfs`

- Matched catalogs (thanks to evevkovacs and fjaviersanchez):
- `dc2_object_run2.1i_dr1b_matched*`
- `dc2_object_run2.1.1i_matched*`

Also, `snr_<band>_cModel` is now available in the new object catalogs (thanks to EiffL).

This release adds the `dc2_metacal_run2.1.1i` catalog and fix the definition of mag_{}_cModel for HDF5 DC2ObjectCatalog. A few other fixes made to the schema for DC2 object catalogs.
