...btw, can we get a version with `:: (FromJSON a) => L.ByteString -> Either String a` as well? :-)

I almost never need the version with `Maybe` as it lacks the error string (since just knowing the decoding fails w/o having any hint whatsoever about why it failed is almost useless for real-world applications IMHO)
