initial tiles route

[abarciauskas-bgse]

Acceptance criteria:

• [ ] A /tiles route which accepts x, y, z path parameters and collection concept id and datetime query parameters and returns a tile by querying CMR
• [ ] Demonstrated working for cmr datasets in /stac/collections/*-cmr.json
• [ ] Automated tests

Pseudo code:

xr_extensions = ('.hdf', '.nc', '.h5', '.hdf5', '.nc4')

# GET /tiles/0/0/0.png?collection_concept_id=C000...&datetime=2000-01-01
def tile(x, y, z, collection_concept_id, datetime):
    results = earthaccess.search_data(
        concept_id=collection_concept_id,
        temporal=(datetime),
        count=1
    )
    granule_link = results[0].data_links()[0]
    if granule_link.endswith(extensions):
        # A place for the CMR reader to takeover?
        data = earthaccess.open(granule_link)
    elif granule_link.endswith('.tif'):
        data = rasterio.open(granule_link)
    # continue with tiling the data...
