Apply oversampling to the ADC values to reduce jitter (OVP / OCP) and LCD readings.

Turn output off if v_in drops below threshold for current output voltage.
Control the fan automatically on DPS5020 to mimic original firmware.

This replaces CC / CV / CL with a CCCV screen.
The use of a SW i_limit is replaced with the HW DAC for limiting current.
This makes the unit behave much like the original, without the SW limit cutting power.
The SW limit is now set to the maximum output current supported by the DPS model.

Be careful with this!
This screen automatically enables the output (so it starts when the solar panel generates power).
It uses a binary tree search to quickly find the maximum power point of the input source.
The output is limited to the voltage / current limits set on the screen.

Change screen colours.
