Refactor Handler to take into account the area for conflicting gestures

[Mrcubix]

Current handling make a Tap or Hold Gesture end if a gesture of the same type with a higher required touch count is started.

For example, starting a 3-touch hold with cause the 2-touch hold to end.

In the situation where the set Area for both don't overlap, they shouldn't be considered conflicting.
This check will need to be performed on Tap & Hold, against all gestures.
