Implement Xiaomi bootloader unlocking in OAI

[hb0nd]

Is your feature request related to a problem? Please describe.
Currently, Xiaomi provides a Windows-only tool called "Mi Flash" to unlock the bootloader of Xiaomi devices. A multi-platform unlock tool would be a big help for those without Windows devices.

Describe the solution you'd like
for Xiaomi devices with locked bootloaders, allow unlocking from within OAI

Additional context
https://github.com/RohitVerma882/termux-miunlock is an open alternative, but still requires a lot of work that the average user might not understand/want to do.

https://github.com/francescotescari/XiaoMiToolV2 also exists, but hasn't been updated and no longer works. it might still be useful to look at the implementation though

Hey, great idea and thanks for the pointers to these tools! Looks like something we might want to include at some point. :)

@tsterbak is this still planned?

I'm aware that this might be a way to go. But it is not strongly planned.
