[Bug]: `get_pourbaix_entries` does not support `solid_compat=None`

[lkkmpn]

Code snippet

with MPRester() as mpr:
    mpr.get_pourbaix_entries('Mn', solid_compat=None)  # ValueError

What happened?

The docstring for get_pourbaix_entries suggests that solid_compat can be set to None:

If None, solid DFT energies are used as-is."

However, the implementation only allows solid_compat to be either one of two supported strings or an instance of a Compatibility class.

Version

0.46.0

Which OS?

• MacOS
• Windows
• Linux

Log output

ValueError: Solid compatibility can only be 'MaterialsProjectCompatibility', 'MaterialsProject2020Compatibility', or an instance of a Compatibility class
