[POWER_API] Need of an explicit function in the power api to change the state of the driver

[luizvilla]

Is your feature request related to a problem? Please describe.
I have created a communication protocol for testing the Twist boards.
My test protocol requires turning the drivers of the legs on and off without activating the switching.
I am now rewriting my communication protocol code and this is not possible natively in the power api code.

Describe the enhancement you'd like
I would like to have an explicit function of the power api that would allow me something like this:

void TwistAPI::disconnectLegDriver(leg_t leg)
{
    if(dt_pin_driver[leg] != 0) spin.gpio.resetPin(dt_pin_driver[leg]);
}

Describe alternatives you've considered
I have considered using the spin api directly. It works, but this means bypassing the twist api, which is not good.
