More compliance with the OLA RDM Tests around sub devices and mute messages.
Get device specific PIDs returning properly in supportedParameters, make the device specific PIDs compliant with the OLA RDM Tests and add device model ID option
Also accept broadcast UN_MUTE messages, but don't respond to them. The spec don't seem to mention this, and OLA hangs when attempting to respond to a DISC_UN_MUTE command with a broadcast address as target.
Device Label is too small to hold trailing null byte for 32 chars, fixed
Increased buffer size to 255
Added way to specify the RDM manufacturer and device ID without having to change DMXSerial2.cpp
Made software version and product category configurable
Added struct to respond to E120_PARAMETER_DESCRIPTION
Added notice where to find the PIDs
Copy the device id properly
