- re-coded mcu_micros
- modified encoder ISR

- added synched interpolator motion flags and controls
- added reverse timer to frequency MCU functions
- modified coolant override (removed form planner buffer)

- modified tool to reside in RAM (function pointers in FLASH for AVR not working)
- added new tools
- tools options now are distinct (COOLING, CONTROL pins, etc)

- interpolator modification for synched motion start
- interpolator realtime motion type identifier flags
- encoder attachable RPM index callback
- g33 incomplete implementation of the sync code

- added pre motion calculations
- accel motion pre calculated to enter constant speed in sync with index

- rpm update coded
- speed change occurs within one step

- fixed planner updated calculations with 2 blocks
- fixed RAMBO board pinouts
- added alarm for spindle failed to sync
- fixed encoder RPM min speed calculations
- added interpolator sync phase condition to start spindle sync
- modified interpolator to lock motion start only on the first entry of the block
- simplified speed calculations for G33
