Odc geo follow throughs

[Ariana-B]

Reason for this pull request

See #1440

Proposed changes

• Complete further aspects of odc-geo migration: replacing GridSpec and some utils.math functions

• Follow odc-geo conventions, and raise warnings where this might be contrary to previous conventions or cause ambiguity

• Also take the opportunity to standardise geobox parameter names where possible, as raised in Standardise geobox parameter names across reprojection functions #1032

• Closes 1.9: Follow through API ramifications from odc-geo incompatibilities. #1440

• Tests added / passed

• Fully documented, including docs/about/whats_new.rst for all changes

Thanks for working through this Ariana.

I'd like to Damien to have a look before we merge if possible.
