Some of the API and paths have changed, so this needs to be updated
accordingly. The most prominent change is the removal of BlobStore and
downloading support from fastboot.js, because a fastboot library should
not be responsible for downloading files.
This simplifies cache busting greatly without needing to do further
processing on any fastboot.js code before deploying. It also removes the
need for a non-module script with global scope.
This implements the WebUSB-based web installer using fastboot.js to
act as a fastboot client. A bare minimum UI with a plain-text
status/progress caption for each step is included, as well as a plain
button to trigger it and basic error handling.
WebADB has been removed now that we are only using fastboot.js.
Initial features:
- Unlocking and locking the bootloader
- Downloading the latest GrapheneOS release available for the device
