Avoids the need to move Motor and Pin vtables into RAM, thus saving
about 20K of precious RAM space.  It also simplifies the structure
of the stepping code dramatically, so it is all in one place instead
of being distributed throughout a complex class hierarchy.

Standard stepper and Trinamic Uart derivatives worked, but Trinamic
SPI driver failed to call their base class's init() method.

The problem was that pulse_func() can do nothing if it is not
awake, and in that case, the _pulse_data variable was holding
old data.

* Fixed Generate_VCXProj

* Moved VFD spindles to their own namespace and inheritance structure. TODO: Configuration.

* Changed the factory a bit to ensure configurations still work.

* This compiles. TODO: Loader script.

* Changed names and made them consistent. This also removes them from IRAM.

* Split out the VFDProtocol code into a separate file.

* Added comment
