Manual Reset button for Flexispot E5B

[jeakob]

Add a manual reset button that simulates a 5-second press of the down button. I am able to reset the 'ASR' error on Flexispot E5B using this method.

This is related to #24

All credit to @KrX3D for the idea.

Great idea! I will have a look on this when I return from holidays.

@jeakob would it make more sense to display this as a button? (single action). Or is there a reason you made it a switch?

We could make it a requirement that the desk is fully down, in order to execute this command?

@iMicknl it makes more sense for it be displayed as a button instead.

My desk sometimes requires a factory reset to fix the ASR error when it is fully up, so that requirement would prevent the reset.
