NewHint#22 shouldn't appear in issue #1031

This can happen because:

• The hint is duplicated with minor string differences in the whitelisted hint list. If this is the case, handle this string match in the cairo-rs HintProcessor.
• We use a different string from the one in the whitelisted hint list. If this is the case, fix the string match.
