Add 5v sensor data capture

[kami-nashi]

Add 5v sensor data inputs
Needs to dump to csv -> DSMUtil friendly
Consider syncing this with the "record" button for ECM link (f12) for better DSMUtil overlay accuracy based on time.
Should be able to scale multiple sensors
Python may be acceptable, unless scaling up requires too much CPU, or timing is problematic -> move to C/C++

Note: Looks like this will need a ADC and/or a Logic Converter. Each sensor will be a 'channel', so considerations need to be made for how many channels per device and how devices chain together.

I have a Logic Converter on order, should arrive on 4/7/2020.

Also, have a pair of ADS1115's on order, also to arrive on 4/7. Allegedly, it may be all I need and some code for it can be found here:
