Flashing with WebUSB?

[ah-]

There is a Web USB flashing tool here: https://devanlai.github.io/webdfu/dfu-util/ that might help making it really easy to install our custom firmware. We could even have a landing page where you just go and click a few buttons to flash your Anne Pro, without needing to install anything besides Chrome.

However, when I tried to use the webdfu tool it didn't flash the firmware correctly and I had to use dfu-util to recover. I think it also showed the firmware size wrong.

Maybe it's possible to fix whatever bugs webdfu has and make it work?
