instrument/touch/top middle bottom calculation

[aburt2]

5G T-Sticks now have 30 touch sensors compared to 16 previously.
Top and bottom areas still seem to correspond to 4 touch sensors (legacy of previous generations). Which means middle section contains 22 sensors!

There should a discussion to decide how the 3 sections should be split and update the firmware accordingly. Older T-Sticks were 4-8-4 (25%-50%-25%).
7-16-7 and 8-14-8 would be closest to existing T-Sticks. Or do we want to go 10-10-10?

@edumeneses I can probably do this quickly over the weekend, the touchsizeedge variable should be computed based on the touchsize rather then arbitrary,

Alternatively I can just move touchsizeedge as a public property and just change it in T-Stick code.

[aburt2]

It would be nicer to define it in terms of percentage to make it easier for others tochange the threshold themselves

Thank you for pinging me again, this issue slipped through the cracks.

We will work on that directly on the refactoring.

Pinging @rochanaf for reference

I'll do a quick fix, just for the folks at IDMIL so the touch behaviour scales with the size of the T-Stick I'll leave more thorough solutions for the refractoring

I will tag this as an enhancement to be added after #16
