Lattice xgboost, a baseline using lattice parameters, space group number, and unit cell volume

[sgbaird]

eXtreme Gradient Boosting trees (XGBoost) is applied on basic tabular data describing the crystal lattice of each compound: lattice parameter lengths and angles, space group number, and unit cell volume. Fixed XGBoost hyperparameters were used. This serves as part of a baseline to answer the question: how much predictive performance is present in the basic details of a crystal lattice (i.e. no composition, no site information)?

This is designed for use on the matbench_mp_e_form task as an alternative perspective in a more established domain (i.e. model accuracy) to that of generative model benchmarking. This is specifically part of a series of baselines and tests related to the xtal2png representation.

@ardunn tests are failing, seems related to matminer.

@sgbaird Thanks for the PR! Let me see if I can fix this and I'll merge this in.

[sgbaird]

Thanks!

[ardunn]

Merged! Not sure what was going on with the tests, maybe some sort of version issue. I was able to pass all the tests of your branch on my machine so it's probably just some CI problem which I'll debug.
