Add a conda environment file that works for Python 3.11

[eguiraud]

The current requirements.txt does not work for 3.11 because of the specified versions of llvmlite and numba.

This might not be the best env for Python 3.11, that is, most packages could probably be upgraded to newer versions, but at least this env runs.

Why is this a conda environment file and not just a requirements.txt as you're installing everything from PyPI? As most of these packages are available on conda-forge is there a reason to not install them from there and then only install any remainders from PyPI?

The idea behind that was fixing the Python version as well, since with the previous file the switch in Python versions caused issues.

I think we should have a single list to maintain though, so if we switch to this, then also drop the old requirements.txt.

If you switch to using lock files then this becomes much easier to even maintain multiple high level environment files and then let the locking system solve the full environment. c.f. https://github.com/iris-hep/analysis-systems-base

This PR is basically just to document that 3.11 does not work with the current requirements.txt and that it does with something like this conda env. I agree this is still not the best setup 😄

@matthewfeickert did you mean to say noxfile rather than lock file? or: what is a python lock file?

aaah found it, https://github.com/conda/conda-lock

This is really more of a problem statement than a PR, so I created #144 to take the place of this PR.
