Add Satisfaction75 to QMK, Enable EEPROM on stm32f072 (#5094)

* Add stm32f072 base ck4x4 to handwired

* add prints

* Save these tries

* Save changes again

* Working hadron oled

* OLEd working but ws2812b still iffy:

* save another try

* Encoder feature + OLED

* RTC code

* Implement clock setting mode

* Whitespace

* Encoder hooked up to working LED PWM code

* Add missing files

* eeprom changes

* Save changes

* Move i2c master

* Move satisfaction75 under cannonkeys

* Set proper default folder

* Revert some core changes

* Undo paved iris changes

* Reorganize code for maintainability and prep for new features

* Add starting code for clock OLED mode

* Clock set mode finished

* Add custom encoder modes

* Actually add VIA keymap

* Gate to only 072

* fix gate for only 072

* Update header guards and includes

* Update i2c selection strategy

* Update board.c to handle software reset to DFU
