Add stacrs as an optional dependency to search stac-geoparquet

[gadomski]

stacrs is a no-dependency Python package that added the ability to search stac-geoparquet in v0.1.3. We could add stacrs as an optional dependency of pystac-client to enable searching stac-geoparquet files.

This was discussed here: stac-utils/stac-rs#462

Note

I am the author of stacrs so I have some bias.

I like that idea a lot. This feels like the current best practice for querying a static catalog #563
