Basic support for restoring the official EV3 firmware. Is missing a video
and needs a bunch of helpful error messages, but basic functionality
is working.
This is just the UI bits (new file template, Pybricks firmware install,
official firmware restore).
The Pybricks firmware flashing hangs because we don't have a EV3 firmware
yet in @pybricks/firmware. Official firmware restore has an alert()
placeholder so at least it does something.
This allows the firmwareFlashUsbDfu to take an arbitrary binary blob
instead of a Pybricks firmware.zip file. This will allow it to be used
to restore the official LEGO firmware as well.
This gives instructions on how to put the hub in bootloader mode like
the install Pybricks dialog and sets the stage for doing the DFU restore
without going to another website.
Issue: https://github.com/pybricks/pybricks-code/issues/1104
This removes the UI and internal support for selecting a file to include
as the main.py when flashing firmware. This feature was removed in the
firmware starting with firmware metadata v2.0.0 so the firmware that
ships with Pybricks code won't be able to do this in the near future.
So, it doesn't make sense to keep this feature only for old firmware.
It is still possible to replace the main.py in old firmware.zip files
and flash that way.
The pattern we were using for actions required actions to be defined in
three places, an enum member containing the type string, an type
definition and a function. This combines all three of these into one by
using a helper function based on the ideas from [1].
