2022 script update

Updates to the plotting script to reshape the script to follow better practices and remove dependence on Pickle and Astropy Tables and move to Pandas dataframe.
Data are now organized in a folder, with the catalog broken into multiple csv files, with each class of object having their own csv table. This is to facilitate contributions and updates.
Fingers crossed, Soon there will be another update, focusing on the data, updating data based on publications since 2020.

Full Changelog: v0.1...v0.2
