correctly (and crudely) simulate control loop
...
Issue was that the ADC cycle half wait (SCK delay) was too fast
for the input buffering (since MISO and MOSI are physical inputs
and not FPGA wires).

more work on control_loop
...
* Make SPI masters internal to control loop module
* Rename commands to use I isntead of alpha
* add ADC value -> DAC value conversion to control loop math

Rewrite control_loop_math and simulate
...
Replace specialized math nodes with single multiplier: each constant
must be resized to fit in the multiplier. Simplifies design at the
cost of speed.
