* Updated indentation in AVR_ATMega4809_Atmel_Studio and AVR_Dx_Atmel_Studio projects, plus small fixes in their readme files. * Added AVR_ATMega4809_IAR, AVR_ATMega4809_MPLAB.X, AVR_Dx_IAR and AVR_Dx_MPLAB.X demo projects. * Removed build artefacts and added .gitignore files in AVR_ATMega4809_MPLAB.X and AVR_Dx_MPLAB.X projects.
