compatibility with STAC>0.7

[scottyhq]

This is a great utility! It looks like this follows STAC spec version 0.5. Are there currently plans to keep in sync with the latest STAC versions? (currently at 0.7 https://github.com/radiantearth/stac-spec).

A couple examples in the readme of searching CMR via this endpoint would be really helpful. For example, this returns an error ('The CMR does not allow querying across granules in all collections')
https://cmr-stac-api.dev.element84.com/stac/search?bbox=[-125,45,-117,49]&limit=10

As an example, can we modify the above URL to search only ATLAS/ICESat-2 L3A Land Ice Height V001 ?

Hi @scottyhq , yes there are plans to update this to the latest version of STAC. Since 0.8 is around the corner (within a month), we will just target that version rather than 0.7.

We are thinking about implementing this as a replacement backend to sat-api, so we leverage the STAC compliant part of sat-api and just replace the elasticsearch lookup backend with the proxy that queries CMR and transforms the responses to STAC Items.

We'll definitely improve the documentation as well!
