"Patching/modifying rapidjson" sounds a little extreme here: the compact
"minified" form that Matlab's jsonencode produces is probably achievable
without such extreme measures. It's just all whitespace elided. (Whether
this can be practically achieved without violating the Matlab license is
another question.)

Given that the JSON spec is kind of loose and there are a lot of
extensions to it, but the base spec is pretty simple, IMHO
byte-identical JSON output is a worthy and maybe achievable goal here.
(Identical decoding behavior on arbitrary inputs is a whole nother ball
game, and I wouldn't suggest pursuing that.)
