Add codespell (workflow and config) to catch typos, fix some caught now

[yarikoptic]

there is one change to the code (siz -> size) -- I hope there is tests, but I do not expect sideeffect there

looking at https://github.com/PySlurm/pyslurm/actions/workflows/pyslurm.yml -- it seems that those Builds were red for quite a while by now... so would be sensible first to fix that :-/

Hi @yarikoptic,

thank your for this addition (I made quite some spelling mistakes I see :) ) I would just go ahead and merge this, if there isn't anything else you'd like to still add prior.

It is fine to ignore the other failing tests, as your codespell action runs in a seperate container anyway. The other tests are there to check whether building pyslurm and the tests work, but the underlying container is not yet updated to support Slurm 23.02.x.

Nothing to add ATM AFAIK
