[MRG] Use CharPyLS fork with newer cython version

[mrbean-bremen]

• should fix Python 3.11 builds
• change Python version for PR tests to 3.11
• fixes JPEG LS support not available under Python 3.11 #1788

Note that I left the note about JPEG-LS not available for Python 3.11, because I first want to make sure that it works, and then either advice to install from source, or add an own pypi package for our fork (which I would prefer).

Tasks

• Fix or feature added
• Code typed and mypy shows no errors
• Documentation updated (if relevant)
  • No warnings during build
  • Preview link (CircleCI -> Artifacts -> doc/_build/html/index.html)
• Unit tests passing and overall coverage the same or better

This seems to work, but I want to first decide about the PyPi package and adapt the documentation accordingly before merging.

[mrbean-bremen]

@darcymason - there is a problem with the doc build, so I cannot view the preview. It looks like you are working on the doc build anyway, so I'm just ignoring this.

I haven't turned CircleCI off yet, so I thought it should still be there, but I haven't checked.

[mrbean-bremen]

CircleCI is building, but it fails with:

reading sources... [ 93%] reference/uid
reading sources... [ 93%] release_notes/index

Exception occurred:
  File "/root/project/venv/lib/python3.8/site-packages/sphinx/ext/extlinks.py", line 103, in role
    title = caption % part
TypeError: not all arguments converted during string formatting
...
CircleCI received exit code 2

This seems not to be related to my changes. I didn't look into the cause, because you are working on the documentation generation anyway.

[darcymason]

Oh yeah, I actually fixed that in the other PR (#1793) ... you could just borrow the additional %ss in conf.py for now, I'm not sure that PR will go through, I was just trying things.

[mrbean-bremen]

Ok, I adapted the name and borrowed your fix for conf.py - I'm done here (I forgot to remove the "[MRG]" prefix, consider it re-added :)

Sorry, lost track of this one. Merging now.

Thank you!
