MegaCoreX v1.0.8

Changelog:

• Fix various bugs and documentation issues with the Event library
  • Add missing static (#106)
  • Don't enable AVR DA/DB specific code
  • Documentation improvements
• Disable pin PF2 and PF3 on the Arduino Nano Every
  • Since these pins are hardwired to the i2c pins (#109)
• Make the i2c buffer size user definable
  • it's now called the same as in my other Arduino cores: TWI_BUFFER_SIZE. With PlatformIO, this can be defined to whatever you want in platformio.ini.
• Remove HID library
  • None of these chips have any built-in USB hardware anyways
• Add SD card library
  • The official library only supports ATmega4809, while this version supports all chips except the 8 kiB variants
• Update Optiboot flash library
• Add Flash library
  • This works as a wrapper around the Optiboot flash library and makes it very easy to read and write content such as variables, structs, strings, etc. to and from flash memory.
  • Note that you'll have to have Optiboot loaded on the microcontroller for it to work
• Update PlatformIO documentation
• Add keywords coloring library
  • You'll now have colored keywords if you write stuff like PORTB in the IDE
• Fix analog pin macro issue (#121)
• Add MEGACOREX and MCUDUDE_MEGACOREX macros
  • May be used by libraries to determine which 3rd party Arduino core is in use
