Implement "rich" output in console and logging

[amoodie]

There is currently a "logger" implemented all over the code, which I guess spits out to a txt file. It would be a good two-for-one to implement the rich console logger (link here), to write to console and to file every time the logger is called in the current code. We should also log to file every time we raise a warning.

Currently, we sometimes print things to console, sometimes log things to file, sometimes warn things, and sometimes a combination of the three. We should make this consistent based on the verbose flag. relates to #40

PR #54 took care of most of this (we have to keep up good practices about logging and printing and warnings though!!).

What's left is to implement the rich printing as suggested on slack. I think this should be pretty straightforward: https://rich.readthedocs.io/en/latest/logging.html

I'm going to rename the issue to reflect this remaining focus.
