Design and build triple bridge driver based on simplefoc shield

[wgbowley]

1. Use simplefoc shield as a reference architectural design
2. Improve design for linear motor specific criteria
3. Construct schematic in KICAD and construct a PCB design
4. Validate that under operating conditions the driver will function

Constraints:

• Current sense has to work at low frequencies. Hence low voltage due to fundamental di/dt being low.
