Add Sentinel Support

[geohacker]

We should support Sentinel imagery from Planetary Computer. Unlike NAIP, with Sentinel we want to allow the frontend decide a time range for creating a mosaic to inference to run on.

I think the inference endpoint will now have to not only take the imagery id/name but also look for a time range which we need to use to query tiles.

@ingalls @vincentsarago let's chat more specifics about this. The frontend design has some implications.

These are the params we want to store:

• date range
• max cloud cover
• data sorting (date / cloud)

We added sentinel support on the backend. Search and store functionality is pending, we'll ticket that separately.
