Rev 0.5.0

Integrated command set_pos to initialize encoder position

Reduced encoder simulation time to be close to real engine speed (1400 rpm),
Added a loop to print position to only 100 time not to overload USB
Ver 5.0

Corrected Encoder simulation timer period to match with real telescope
Rev 6.0.0

NOTE you can go back to rev 5.5.1 which is a stable one uncommenting some instructions and using a thread to simulate the encoder (still used but with separate synch semaphores).

Merged Encoder normal and debug modes.

Clean up #define and #ifdef
