Simplify dependencies

[user202729]

The whole jupyter is not necessary to run this, just these 3 appear to suffice. (tested in a virtual environment, but looks like jupyter is not really well-isolated so jupyter-console seems to still work in the virtual environment even though it's not installed in there, not sure)

The latter 2 is a dependency of ipykernel in fact.

I like to keep it simple, i.e. I prefer having a single dependency instead of three dependencies.

I also like to keep it more future-proof, i.e. I want to reduce the chance that things break in the future. I'm not 100% sure those three separate packages will stay the real dependencies for the next few years, or maybe they change their internal structure and the packages get renamed, or maybe some other packages become the new dependencies.

Also, how important is this? How much bigger does the dependency get by installing whole jupyter? How realistic is it that a user does not want to install just all of jupyter?

At it happens, in my current installation I only install IPython which drags along enough to run this, but not the whole of jupyter. I think IPython itself is relatively frequent.

At the moment if I install jupyter-notebook in addition it will install the following on my Arch Linux machine (I already have IPython and jupyter-console installed):

Yes, these are valid considerations. Up to you.

Thanks for the information. Maybe we just use this now and once we see sth breaks with the dependencies, we revert back.
