Allow timeout for sending PWM signal to servos

[TD-er]

As discussed in this thread on the forum: Release/Stop Driving Servo?

Suggested implementation:
Allow 2 thresholds to get 3 ranges, with for each range a timeout to keep sending the last value.
Of course changes should be sent immediately.

Should the timeout be in msec or in samples?

Also on the forum this suggestion for improvement with PWM control via MQTT: Wemos D1 mini and flickering PWM

Hi,
I would like to have msec. I will use this feature for a ventilation flap that operates about 2...10 times per day. For the rest of the time the friction of the servos is high enough to hold the flap in position.
Thank you.

This seems to be solved, so can be closed.

Not 100% sure the timeout of the PWM is present.
You can send a specific (documented) value to the servo command to stop sending the PWM command and thus keep the servos from actively correcting their position and thus heat up (burn out?)

Since this feature is present, I guess there is no need for a timeout option for the servo command as it is possible to 'quiet' the servos.
