Issue:
implement STAC API Query fragment
For STAC providers, STAC API Item Search has limited filtering capabilities (`collections`, `ids`, `bbox` / `intersects`, `datetime`).

However, it does not contain a formalized way to filter based on arbitrary fields in an Item. For example, there is no way to express the filter *"`item.properties.eo:cloud_cover` is less than 10"*

This can be improved using properties filtering provided by the [STAC API - Query Fragment](https://github.com/radiantearth/stac-api-spec/blob/master/fragments/query/README.md)

*Note that it is planned to be deprecated in favor of [STAC API - Filter Fragment](https://github.com/radiantearth/stac-api-spec/blob/master/fragments/filter/README.md), providing CQL filtering. But for the moment, available STAC API provider do not support  it.*

Pull request:
feat: stac api query fragment usage
fixes #354 

Implements STAC API `Query` fragment.

*Note that it is planned to be deprecated and be replaced with `Filter` fragment. But for the moment STAC providers `earth_search` and `usgs_satapi_aws` are using it (`astraea_eod` do not use any of the 2), so we go for `Query` fragment and will update to `Filter` when needed.*
