Features
* drop python3.8 support. by BrianPugh in https://github.com/BrianPugh/gnwmanager/pull/245
* `gnwmanager flash-bootloader` can now automatically download and flash bootloader from https://github.com/sylverb/game-and-watch-bootloader
* `gnwmanager flash-patch` can now do most common nintendo-firmware-patching functions. Users will no longer need to separately use https://github.com/BrianPugh/game-and-watch-patch.
* All keystone-engine commands are pre-computed, meaning that users won't have to install this dependency (can be non-trivial on some raspberry pis.)
* All custom code is pre-compiled, so no user-side compilation is performed.
* Also integrates nicely with SD card support via the `--bootloader` flag:
