Detecting Talon SRX and Victor SPX

We’ve been using this code to detect the absence or presence of devices on the CAN bus and reconfigure to match (we don’t have our competition and test chassis matched up yet).

This code broke (doesn’t see the controllers) when we put new firmware on the SRX and SPX. Controllers are present (Phoneix Tuner sees them). Did the CAN message ids for the controller status change with the 2019 firmware?
