Windows again.

- pretty much the same as last time, except it was way easier to add now thanks to the code restructure - baseband will not be touched and will be intact this time, unlike before when baseband gets downgraded to the 8.4.1/6.1.3 version - it's still worse than futurerestore though, just use ota downgrader on linux/macos instead please
