GFromForm for Bool

Hi, I’m wondering if it’d make sense to have a special handling for Booleans in GFromForm like we have for Maybe. It’d make sense to write an instance that parses like `Maybe` but `@Text` and then fmaps with isJust st a checkbox can be recognised without checking their value or encoding it as Maybe Text on the Backend. Perhaps a newtype like “CheckBoxParam” or something with the same name that’s isomorphic to Bool would be worthwhile as well?
