Serialized ATN generation changed.

Originally the serialized ATN was coded as a wide string literal with embeded Unicode escapes (where necessary). This might fail on Windows however, as VS is very strict when checking Unicode code points and rejects compilation if it finds undefined code points. Hence this generation has been changed to hex numbers instead of that string literal.
