A bestiary of minimal paleoclimate models and the scars that taphonomy carves on their hides

General Structure:

• Signal: this class will generate a pure (noise-free) series based on a given model. For instance model='Ganopolski2024.Model3' or 'Ganopolski2024.MiM'. Need to think about how to pass inititial conditions, boundary conditions, and model parameters. Giant dictionary exported to a yml file for traceability? Signal should be a Pyleoclim series (trivial to export to csv, if one needs to).
• Noise: this class will add various noise colors to the signals. Should also use pyleo.utils.tsmodel.random_time_index() to mimic the time sampling process, and create irregularly sampled series with reasonable characteristics.

Jordan is on the signal, Alex is on the noise.
