The expected version can now be set in the Makefile via USR_CXXFLAGS.
Additionally, the README.md has received documentation regarding the
version check. Lastly, the version check can now be disabled by omitting
the flags or setting one of them to a negative value.
When a MasterMacs motor is powered for the first time, it does not have
a target set. Therefore, the targetReached bit is 0, which the driver
used to interpret as "moving". This is solved now by an additional flag
which checks if the motor did a handshake.
Additionally, the communication module was simplified and new utility
scripts were added. It is now made sure that the communication timeout
for enabling and sending move commands is now at least equal to
PowerCycleTimeout defined in src/masterMacsAxis.cpp.
