Introducing COSMICOutput

[TomWagg]

I went a little rogue and got carried away here but I think you'll like it @katiebreivik.

This PR introduces a new class in cosmic.output.COSMICOutput. This class lets you do things like:

• Instantiate based on evolve output `output = COSMICOutput(bpp, bcm, initC, kick_info, label="Latest run")
• Save and load from a file output.save("file.h5"); new_output = COSMICOutput(file="file.h5")
  • This will also track the COSMIC version and warns users about mismatches
• Index and mask the class to get specific binaries based on bin nums or masks
  • randos = output[[0, 1, 2]]; randos = output[10:20]
  • `massive = output[output.initC["mass_1"] > 10]
  • This will mask all of the relevant dataframes
• Re-run with new physics
  • alpha_5 = output.rerun_with_settings({'alpha1: 5}, inplace=False)
• Plot all sorts of stuff
  • output.plot_detailed_evolution(bin_num=0)
    • This uses a bcm table, can pass kwargs to plot_binary_evol
  • `output.plot_distribution(x_col='mass_1', y_col='mass_2', c_col='porb', when='initial')
    • This one uses either initC or bpp based on whether you say "initial" or "final", it can also do histograms if y_col=None

There's also a whole new tutorial in the docs that explains/demonstrates this all in more detail.

Happy holidays 🙃
