Improved dataset control

[chrisiacovella]

Pull Request Summary

This provides changes aimed at improving the control over datasets. Specifically, the switch to .toml files meant we could not easily toggle which properties to load from the hdf5 files nor which properties to assign to the key internal variables (energy, force, dipole_moment, etc.).

This updates the pydantic dataset model whereby users now additionally define properties of interest (as a list) and then the association of these properties to the internal variable names (i.e used by the Properties class). The pydantic model validates that anything in the Properties association also exists in the properties_of_interest list. We do not validate that the properties_of_interest are actually in the hdf5 file via the pydantic model; this is handled when we assign those parameters while calling the DataModule class. Since this is one of the earliest steps in the process, failure to properly define these should lead to a rapid failure. this saves considerable extra code in the pydantic model, and having to make separate models for each dataset.

Key changes

Notable points that this PR has either accomplished or will accomplish.

• Allow better control over datasets via .toml files
• Fix buffer issue when logging to wandb
• Fix logic whereby using dipole moment in the loss required total charge as well (since dipole moment requires charges. This is fixed such that charges are calculated if dipole moment is requested, even if total charge is not in the loss).
• bug fix to spice1_openff curation (wrong tag for scf_dipole).
• change backend for matplotlib to prevent issues when using debugger
