The encoded data is a sequence of runs, where each run consists of a length byte followed by 1 to 128 bytes of data. If the length byte is in the range 0 to 127, the following length + 1 (1 to 128) bytes are copied literally during decompression. If length is in the range 129 to 255, the following single byte is to be copied 257 - length (2 to 128) times during decompression. A length value of 128 denotes EOD.
