RunLengthDecode filter. Never used in practice.
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.
