Compatibility fix for passing odc-geo GeoBoxes to dc.load(like=...)

[robbibt]

Reason for this pull request

Support users passing odc.geo GeoBoxes to datacube.load(like=...). For more details, see #1549.

Temporary fix until odc-geo is officially integrated in version 1.9.

Proposed changes

If the passed object is not a Datacube-style Geobox but has a odc-geo ".compat" attribute, try using that ".compat" method to convert the odc-geo style GeoBox to a datacube-style GeoBox.

(I deliberately didn't use a check for whether it was the object was a odc.geo.geobox.Geobox object because I didn't know if we wanted to add odc-geo to the package dependencies yet - happy to change to that though if you'd prefer!)

• Closes Cannot pass odc.geo GeoBoxes to dc.load #1549
• Tests added / passed
• Fully documented, including docs/about/whats_new.rst for all changes

Thanks Robbi - would be good to have a test though.

It should be reasonably easy to write a test without installing odc-geo - because of the way you wrote it you could just pass in a mock with an ODC-GEO GeoBox as the compat attribute.

@SpacemanPaul Let me know what you think about this approach - I couldn't get MagicMock to work without infinite recursion errors, so went with making a fake class instead.

Looks good. Thanks Robbi (and Kirill)
