byteify-strings: add --treat-as-kwargs argument to handle kwargs-like objects
This argument will help extensions move to Python 3 as keyword arguments
should not be byte-prefixed. Most of the time, code bases will call this
object `kwargs`, but other conventions exist like `opts`, so it should make
sense to allow for custom names.
This is a best effort solution that does minimal static checking; cases like
`options = [o for o in ('a', 'b', 'c') if kwargs.get(o)]`
and other just as complicated will not be detected.
