Change code in pushbuttons to avoid warnings when pushbuttons are not enabled
Add choice of find index using LDR or using STEP counts
Add machine states to handle case 21: move motor steps and a halt command (only for setup of filterwheel)
Use seperate code paths for handling find index and move to slot
Rewrite all classes to have an explicit start() function (not having setup code in class constructor)
Rewrite serial comms class, link Arduino serial event to execute class serial event
Fix error in void FilterWheel::reset_filterwheel(void)
Fix debug code
Fix swap in init code for led/ldr 
Fix for LED not turning on/off
Fix for find index code
Fix for homeonconnect and homingmethod code
Fix for motor enable/disable not being in correct state for moves
Fix for write to eeprom not waiting for MYINTERVAL to occur

200-02 16-Jan-2022
Add FINDHOMEMETHOD to controllerconfig.h
Move HOMEFOUND - ldr value indicating slot 0 - to myFilterWheel class
Fix for case state_move_to_home: use myfilterwheel->get_maxsteps() instead of MAXSTEPS
Fix for home pushbutton not working correctly
Fix for Move Slot 0 returning immediately
Fix for Find Index not updating slot number when index is found

200-01 09-Jan-2022
Add maxsteps
Rewrite logic for find index, add additional states for state machine
