Add optional dependencies

[fabcor-maxiv]

GitHub: fixes #885

[fabcor-maxiv]

This is kind of an experiment. I do not know if it will go well or not, but I believe it is worth trying a bit at least.

So far I managed to add quite a bit of optional dependencies. Some are still missing.

Adding bliss is problematic, Poetry can not solve the dependencies. I will see if I can find a way to help Poetry with that.

Poetry (under both Python 3.8 and 3.9) ends up failing on trying to install fisx.

Should we keep this one open ?

Should we keep this one open ?

Depends if it is a worthwhile task or not...

I think it would be good to have all dependencies listed. I do not know how others handle deployment if not all dependencies are listed. How do facilities know what needs to be installed? Where do they keep their list of dependencies?

This is something I am interested in. This is something we discussed a bit in our breakout room at the code camp, but did not manage to get to the bottom of things. Maybe the questionnaire we worked on, could help shed some light on this. But on the other hand, if everyone is happy with things as they are, then maybe I can focus on MAX IV dependencies only and ignore the rest.
