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.
Added a custom timeout for the enable command, as it takes quite a bit
of time for the motor controller to answer and we don't want to show a
premature communication timeout error. Also changed the code in order to
use the motorPosition() and setMotorPosition() methods instead of
directly accessing the paramLib.
