Add simulated data from different simulations

[anicola]

Currently, we're using synthetic data vectors from Abacus. It would be nice to use other simulations as well, e.g. cosmoDC2, Aemulus.

This is the wishlist of what we would need:

Measurements of Pgg(k), Pgm(k), Pmm(k), PmIC(k), PgIC(k) and PICIC(k) for:

• A set of ~9-10 redshifts sampling the range 0 < z <~2-3 reasonably
• One or two galaxy samples. We can provide HOD parameters for our proposed samples, but anything else reasonable is probably useful.
• A reasonable range of scales (e.g. ~0.001 < k*Mpc < 1-10)

Above 'g' stands for the galaxy overdensity, 'm' for the matter overdensity, and 'IC' for matter overdensity in the the initial conditions (or at a sufficiently early time).

Tagging @j-dr @cwwalter. Let us know if there's anyone we could/should approach about this.
