PC Engines APU firmware tool

PC Engines APU firmware tool: firmware dumper, restorer, auto downloader and updater.

under the hood is verifies the checksums, auto download the latest firmware, detect board mismatch of the same apu model, preserves bios settings if possible. And other quirks as choosing the best reboot method... detecting tools needed.

Tested intensely with a range of firmware version on APU4.

Anyway enjoy!
