Support for Nice!Nano V2 Nordic nRF52840

[astrolemonade]

Hey!
Thank you for creating this library!
Can you add support for Nice!Nano V2 Nordic nRF52840 https://nicekeyboards.com/nice-nano?
There are a schematic and a pinout for it: https://nicekeyboards.com/docs/nice-nano/pinout-schematic for both V1 and V2(but only V2 is still commercialized). There is more info here: https://nicekeyboards.com/docs/nice-nano. It is mentioned that the board is using https://github.com/adafruit/Adafruit_nRF52_Bootloader bootloader.
I would gladly help with testing if you decide to add support for it.
Thank you!
