Change references to BLDCDriver to FOCDriver in current sense base class

change setPwm function in FOCDriver to accept 3 args, with a default value for the 3rd

Change stepper driver classes to use 3 arg setPwm, ignoring 3rd arg.

created InlineCurrentSenseSync class in lib/currentsense.

fixed timer bug in calibrate encoder, in main

defined a label for serialusb, to make it easier to swap out.
