Up to 27% faster for Ping360 on 2M baud serial connection

updated calculate_checksum to use built in sum instead of manual loop
added __slots__ to PingParser
updated parse_byte to directly call the relevant function for the current state
added ERROR status code to be in line with ping-cpp

Helps with #101 (although Python's I/O can't really ever be completely as fast as compiled code).
