Some improvements we may want to make to the code

[x] Make the name of the fit output folder the same as the name of the runcard instead of "fits"
[ ] Make code more user-friendly by storing info in dataclass objects instead of dicts
[x] Make a default folder to store the fits, so the path doesn't need to be passed each time plots are made
[ ] Make a single interface for all plots
[ ] Add the option to either use patience_epochs or patience_fraction to the runcard. Current stopping_patience is in epochs, which is different from n3fit where it's a fraction, this might lead to confusion
[x] add a generate_pseudodata boolean flag option to the fit runcard
[ ] Make names in callbacks.py more sensible
[x] do feature scaling outside model, this will also affect how models are saves/loaded
[ ] Stop rich from messing with ipdb
[ ] related to above, just print chi2 info line-by-line so the logs contain a history
[ ] make gradient descent stochastic to reduce computational costs
