t2u : Improve t2u detect algorithm much much better
The bad algorithm due to import from dt2w and some bad implementations by me
Improve it to the best possible , by simplifying the algorithm
removing unwanted stuffs

fix loopback problem
touch count : 1 2 3 4
input value : 2 3 4 1

now its more accurate and works after a single pattern input after deepsleep

enable check time gap between every two touches
if long then clear previous touch and consider the 2nd as the first
