Currently load_stac relies on the stackstac library, which works fine until we try to load more complex types of STAC objects.

As far as I am aware, current limitations of stackstac are:

Can load only single band COGs: multi-band geoTIFFs are not supported
Can't load STAC based on netCDF data
Always load the data as Float64: Use data_type and nodata from raster extension if present gjoseph92/stackstac#91
Can produce a shift in the data: Stackstac.stack provides shifted pixel coordinnates compare to qgis/rioxarray gjoseph92/stackstac#207

This limits the functionality of the implemented process. I will investigate the possible switch to either:

odc-stac: regularly maintained and updated
- Currently doesn't handle scale and offset automatically: Scale/offset with raster:bands.{scale|offset} opendatacube/odc-stac#55
xpystac: based on both stackstac and odc-stac
