This may be necessary in case SDF ligands have the same chain/residue
number, which can happen with some input.

This should clarify what the binding site.

Enables the full scoring experience with CAD score

- Tell the user that biounit indices are 0-based
- More info in output on what chains are actually processed

Corrupt residues may have some properties missing => Select("peptide=true")
may give an empty view.

Avoids issues in query language when funky characters appear in chain names

The previous error was a selection statement with no obvious connection to
that problem. Default minimum lengths are 10 for peptide chains and 4 for
nucleotide chains

AFDB v4 files are invalid as there is a mismatch between _citation.id
("primary") and _citation_author.citation_id ("1"). This can now be read
by setting fault_tolerant=True. In this case, a warning is logged and
no authors are set.
