Calculate and Plot Reading of a Water Well Sensor

Simple software made for aiding in calculating the values that an analog voltage sensor will read from a series resistor
in a water column height sensor with a constant current output. The analog sensor happened to provide its output value
in percentage to the web API.

Used for a particular setup where a Shelly 2PM + AddOn Plus was reading the voltage of the resistor.
