ProjectionExtension v2 (proj:epsg -> proj:code)

[jsignell]

Related Issue(s):

• Support for projection v2.0.0 extension #1286

Description:

The intention of this PR is to still support using epsg and just store it in proj:code.

Note

This PR removes epsg as a positional argument to ProjectionExtension.apply. It also removes all positional arguments to it should raise nice errors for that scenario.

Another option would be to allow positional arguments and automatically deduce whether they should be interpreted as epsg or code based on type. I suspect that using epsg as a positional argument in apply is rare, so I strongly prefer the approach in this PR.

TO DO:

• get summaries working properly (waiting on Add proj:code stac-fields#27)
• remove local override of projection extension (waiting on Adds support for IAU codes. stac-extensions/projection#12)
• add explicit tests for old versions of the extension

PR Checklist:

• pre-commit hooks pass locally
• Tests pass (run scripts/test)
• Documentation has been updated to reflect changes, if applicable
• This PR maintains or improves overall codebase code coverage.
• Changes are added to the CHANGELOG. See the docs for information about adding to the changelog.

Just checking in on this, is there a date by which the change to support proj:code instead of proj:epsg is expected to take effect?
