This has a more modest impact than that mentioned in issue #169, but a make benchmark reports 1.5-2x speedup on string dumps.

Sorry, something went wrong.

Uh oh!

@lelit
Implement an optimized version of the string serializer

This resurrects (part of) the optimization implemented by Ken in commit
697c15c, specifically the second half
where it avoided the need to "[...] convert into a codepoint, just get
the hex chars from the bytes directly", given that the code deals with
well-formed UTF-8, guaranteed by Python internals.

The other part of the original commit has been absorbed by underlying
rapidjson library.
