I need a function which will parse one floating-point number from the string, given the index of the first byte. Does Lua's library provide this?

I faced this problem a while ago when trying to decode some doubles in
OSC. It was pretty surprising to hit such a brick wall, I'm thinking
the easiest way would be either bitops or a proper pointer cast in C.
