Use TQDM trange and postfix for better loading bars or move to richtext

[SamTov]

We can use the TQDM trange, postfix, and set description to update the description of our loading bars at each iteration. This means we can include more information iteratively such as ensemble number, ensembles per second, and other important parts of our computations which should improve the clarity of the operations.

EDIT

I found the richtext loading bar after this issue. They look much nicer.
