Added Menu to control_loop_sim.cpp
...
I was able to add the menu to the file and I fixed some bugs that came up.
For some reason the seed value (a.k.a. P value) does not accept strings or char values so I left the set_value
as is and same for the I value I don't know what the value is that is within the set_value. But everything seems
to work the way it's intended to.

Issue was that the ADC cycle half wait (SCK delay) was too fast
