Servo motor current monitoring

Trickier than I thought because when starting, servos draw a peak of current similar to when there is an obstacle.

This could be mitigated by software strategies, like computing the derivative of the current variation, etC.

In my test I was using INA169NA CIs and 0.1 Ohm SMD resistors with this schematics on each servo, using 5 DAC inputs from esp32.
