Prevent computer/device from sleeping while uploading

[mifi]

Problem

While uploading a large file, the computer or phone might go to sleep, we should prevent this

Solution

We could use the WakeLock API but it seems to have limited browser support.

Maybe we can implement a <video> tag with a looping 1-pixel video or so. https://stackoverflow.com/questions/59471449/how-to-prevent-screen-sleep-using-javascript

Need to find out how to detect when the browser activates sleep prevention (logs, enable debug logging, operating system logs?)

We could make an Uppy plugin that uses the WakeLock API by default, but with an optional (configurable) fallback to some hack like video/audio tag or similar

Alternatives

Allow the upload to resume if it’s interrupted by a sleep or similar. However that is a different issue that should also be fixed regardless of the current issue. See #3783
