Support Python 3.11

[martinvonk]

Now that Pastastore supports python 3.11 (https://github.com/pastas/pastastore/pull/93), HydroPandas should be fine as well.

The current issue fail on py311-ubunti seems to be with Linux installation. Maybe you can shed some light on this @dbrakenhoff ?

I can reproduce the issue locally. It has to do with the netCDF4 package being pinned at 1.5.8. Removing this version requirement I can install the package, but it was put there for a reason so we should check why that was.

[dbrakenhoff]

Some flake issue is now causing the test to stop. Leaving that fix to you @martinvonk :)

My specialty, thank you :)
