Olivier Poitrey 447d0fc7f5 Optimize JSON encoding even further
Last optimization was for JSON string with no character to encode. This
version focuses on strings with some chars to encode, trying to apply
the same trick for substrings that do not need encoding.

Josh Baker f8aa7a1962 Optimistically expect simple strings for json (#6)
Performance update to appendJSONString so that it now checks if
the input is a simple string that contains no json delimiters, control
characters, or unicode. If simple then the operation is only three
appends. [double-quote, string, double-quote].

If a non-simple character is encountered then all of the previous
characters are appended and the operation falls back to the original
method for the remaining characters.
