ENH: warn when export of CRS returns None

[martinfleis]

• Part 1 of Export as WKT1_ESRI or WKT1_GDAL silently returns None for custom CRS #1036
• Tests added
• Fully documented, including history.rst for all changes and api/*.rst for new API

Mind adding a warning filter here:

pyproj/pyproj/crs/crs.py

Line 447 in ce9de36

auth_info = self.to_authority(min_confidence=100)

?

[martinfleis]

All done.

I don't think that I caused this CI failure.

I agree. Looks like a jinja2 issue with the docs build that is unrelated.

@martinfleis, this looks great, thanks again👍

Would you like to squash your commits or would it be fine to squash & merge?

#1038 should address the docs build issue.
