Multi Touch Input

[il-Grigio]

• I have checked that a similar feature request does not already exist.

My problem is that I would like to use scrcpy to play a few games on my PC, but some of them require multiple touch inputs at once, and the PC handles only one mouse, I would like, if possible, to remap come keyboard keys to a touch or an action in a specific screen coordinate.

Keyboard mapping: duplicate of #712

(Note that if your computer supports touch input, multitouch is correctly forwarded to the device.)
