redesigned the input protocol to be a 3-byte sequence, the first byte is the

data type, the second two are the data.  The second two bytes are then
combined to give one 14-bit value.

 For example 240 0 1 (from serial) == [version 1( (Pd message)

arduino-test.pd was updated for this, the help patch was not, but should be
largely correct.  I only tightened up the layout of the help patch.
