Update input vars plots

This MR adds some new features to the input variables plots for the tracks. Also some small update for the pT vs is given.

1. Updating the config for input variables. The plots are now more customizable. Also rebuild the plot function for the track input variables. For usage, documentation is provided.
2. Erasing doubled code from the dips plot config.
3. Small update how to give an evaluation file path to the pT vs function.
4. Adding option Same_WP to pT_vs function. This will calculate the WP for one model in the comparison plots and use this for all other models.
5. Also adding the input_var_tools to setup so they can be used correctly.
6. "Merging" Maxence plot input function for the jet variables. Are now compatible with the new track one and also documented.
