Update some of the data files

[CompRhys]

Changes to make:

• Fixes to NaN issue and Formula in mp_energies -- avoids duplication of

df_mp = pd.read_csv(DataFiles.mp_energies.path, na_filter=False)
# TODO get the real formula from the Composition rather than rename.
df_mp = df_mp.rename(columns={"formula_pretty": Key.formula, "nsites": Key.n_sites})
df_mp.loc[
    df_mp[Key.mat_id].isin(["mp-1080032", "mp-1179882", "mp-1009221"]), Key.formula
] = "NaN"
assert len(df_mp[df_mp[Key.formula].isna() | (df_mp[Key.formula] == "")]) == 0
df_mp = df_mp.set_index(Key.mat_id)

• replace "wyckoff" and "iso_wyckoff" column names with updated names "protostructure" and "prototype"
• Add magmoms to DataFiles.mp_trj_extxyz.path as seemingly missing for MPTrj EDA. they can be grabbed from the results dict (see Restore MPTrj EDA to working order #130)

This is just running list to be actioned at some point in the future
