Other summary statisitcs

[modichirag]

This issue is to keep track of other summary statistics that can be implemented.

To begin with, here is some code from other project to estimate statistics-

• power spectrum code for Quijote simulations. There is also code to implement simple HOD models with this. https://github.com/modichirag/contrastive_cosmology/blob/main/src/hodtools.py

• code to estimate wavelet coefficients. At the moment this has only been tested on continuous density field like dark matter fields, but maybe will be okay for first implementation on halos as well? https://github.com/modichirag/contrastive_cosmology/blob/main/src/wavelets.py
