Add finger present API and bit. Update README #212

Open secworks opened 2 months ago

This PR adds the ability for SW to read the sampled input from the touch sensor. That allows SW to detect a finger present, and with the aid of the timer measure touch events of different lengths.

Maybe closes #214

Rebased on main and added the addresses in tk1_mem.h.

Also did an implementation in tkey-libs, see the draft PR.
