Update for pyarrow 21.0.0

[AlenkaF]

In PyArrow version 21.0.0 PyExtensionType will be removed, see apache/arrow#46199. We need to update the checks in __init__ so that the hotfix doesn't break with future pyarrow versions.

Hi @AlenkaF , two things:

1. can you merge from main to fix existing CI tests (I had to update them to account for GitHub Actions runner updates)
2. can you check the hotfix tests run with PyArrow 21?

Done.

can you check the hotfix tests run with PyArrow 21?

With the last commit and hacky diff for local dev setup:

the tests passed.

Adding package info, just in case:

>>> pip list
...

It seems this needs to be fixed for PyArrow 0.14, see CI failures.

[AlenkaF]

Plan to have a look at it tomorrow/Friday. Thanks!

[AlenkaF]

@pitrou pinging for CI approval.
