Implements an input driver utilising the MPR121 Touch IC and is compatible with common MPR121 keypad PCB's.
- Implements a "candybar" phone style 12-key keypad
- multiple taps to rotate through the character set
- longpress for navigation keys
- keymap to allow arbitrary routing of MPR121 pin to button configuration
- extendable to other key functions
- Integrates with the existing kbI2cBase implementation
- Works with CannedMessageModule Freetext mode
- Can be used with common MPR121 boards, such as https://www.amazon.com/MPR121-Capacitive-Keyboard-Buttons-Sensitive/dp/B083R89CHB/ref=sr_1_6
- Of use for PCB based radios, where some form of low surface area low component freetext input is required, but also without consuming too many IO pins.
- Tested on a T3S3 connected to Wire1 (Second) interface.

* support BB Q10 keyboard
* remove debug code
* fix wrong logic
* fix left/right keys for cardkb
* Try to enable Q10 kb after all
* cppcheck
* Only fire on Key release and assume 0x0a is a enter as well

* Break i2cScan out into a set of classes for scanning i2c
* refactor i2cscan addresses to be structs that allow addressing by port + address
* build whoopsies
* trunk fmt
* trunk fmt
* lost some build fixes from the merge
* more cleaning for build safety, RTC behavior
