Sanitize format - Zero terminate so extra characters after format (e.g. "%f123") don't confuse atof/atoi - stb_sprintf.h supports several new modifier

- For scanning we need to remove all width and precision fields "%3.7f" -> "%f". BUT don't strip types like "%I64d" which includes digits. ! "%07I64d"

Extract the format out of a format string with leading or trailing decorations fmt = "blah blah" -> return fmt fmt = "%.3f" -> return fmt fmt =
