MagicHeaderAndLengthByteTransformer class
Assembles messages that start with a fixed sequence of zero or more magic bytes followed by a single byte that indicates the length of the rest of the packet. null is accepted as a wildcard byte.
example null magic (will match any header byte)
0x60 0x03 0x01 0x03 0x02
0x10 0x04 0x01 0x02 0x03 0x04
Will clear input if no data is received for at least 1 second.
