adding Hadron v3 keyboard, QWIIC devices support, haptic feedback support (#4462)

* add initial support for hadron ver3

* add initial support for hadron ver3

* pull qwiic support for micro_led to be modified for use in hadron's 64x24 ssd1306 oled display

* initial work on OLED using qwiic driver

* early work to get 128x32 oled working by redefining qwiic micro oled parameters. Currently working, but would affect qwiic's micro oled functionality

* moved oled defines to config.h and added ifndef to micro_oled driver

* WORKING :D - note, still work in progress to get the start location correct on the 128x32 display.

* added equation to automatically calculate display offset based on screen width

* adding time-out timer to oled display

* changed read lock staus via read_led_state

* lock indications fixes

* Added scroll lock indication to oled

* add support for DRV2605 haptic driver

* Improve readabiity of DRV2605 driver.
-added typedef for waveform library
-added unions for registers

* Update keyboards/hadron/ver2/keymaps/default/config.h
