Using rich for a more friendly terminal experience

[Remi-Gau]

Started trying to annotate some datasets and wondered if using some more user friendly terminal output could not help.

try to add rich as a dependency and dropped a
from rich import into nidm/experiment/Utils.py and started getting some markup that already helped a bit (see below).

I can try tweaking things a bit more and PR it if you are interested.

FYI

I have pimped the terminal user interface for my own use.

It lives in this branch: https://github.com/Remi-Gau/PyNIDM/tree/friendly_TUI

Let me know if I should make a PR out of it.
