Firmwares for encoders newer than MT8173 will include an ABI version number in their initialization ack message. Add the capacity to manage it and make initialization fail if the firmware ABI is of a version that we don't support. For MT8173, this ABI version field is reserved and thus undefined ; thus ignore it on this chip. There should only be one firmware version available for it anyway.
