* Add Lilygo T-Impulse-Plus

* Enable small screen layout 64x32

* trunk'd

* Haptic Feedback (short and long press)

* enable Charging Indicator

* enable nrfutil uploads

* trunk fmt

* enable proper device model

* Dim the haptic duration a bit.

* Fix GPS pins and speed. Module enable is active low, speed is 38400

* Potential fix for pull request finding
