'''---------------------------------------------------------------- sysextest.py
This is a quick and dirty debugging console for a midi device.
It recieves sysex messages sent the the dev id 0x7d 0x33 0x33 and decodes and
prints them. The messages are encoding using the intel hex format because
I planned to use the same format to transmit data to and from a bootloader.
Currently the sender is not identified however the address and type fields are
avaliable for this purpose.
In addition it also sends and recieves the Univeral midi sysex id request.
