RunLength format consists of a sequence of a byte-oriented format based on run length. There are a series of "runs", where a run is a length byte followed by 1 to 128 bytes of data. If the length is 0-127, the following length+1 (1 to 128) bytes are to be copied. If the length is 129 through 255, the following single byte is copied 257-length (2 to 128) times. A length value of 128 means and End of Data (EOD).
