Initialization bíður 2 s, mótor stöðvast alveg, hreinsun

- InitializationState: 2 s bið með millis() án þess að blokka, Boot-up sent í exit()
- MotorDriver: PWM-pinnar aftengdir frá Timer2 þegar þeir eiga að vera LOW
  (OCR=0 í Fast PWM gaf samt stuttan púls)
- Eytt útkommentuðum skrám: main_P2, temporary_main, rotary_encoder_driver_unused
- .gitignore: plot-skriftan fer í git, vélarsértækar PlatformIO-skrár út
