Bingo PgSQL checkMolecule function doesn't check implicit hydrogen count

This is a minor issue, but when Bingo is indexing molecules, I think it's the cmf_saver that checks that implicit hydrogen count is sane, i.e. <=10.
The bingo.CheckMolecule() cartridge function however does not indicate any issues with these molecules as this is not one of its checks.
I expect most users will not have input that causes this issue :-p

Start by locating the Bingo PostgreSQL cartridge implementation of bingo.CheckMolecule() and compare its validation with the cmf_saver check for implicit hydrogen counts. Confirm the expected limit from the issue, then identify the existing Bingo test entry point or add coverage where this behavior is tested. Done means CheckMolecule reports molecules whose implicit hydrogen count exceeds the accepted limit.
