Add support for generating low lights videos for a specific player

[ReneRebsdorf]

What problem is this solving

When I want to review faults, save this to a video file I currently have to use the "watch -> low lights" feature, and manually record the video using OBS or similar.

Proposed solution

It would be great if there was a "Death" event similar to the "kill" event in the "Generate Player's sequence" option.

Describe alternatives you've considered

Using OBS when playing the "low lights" demo, stopping the recording when done, and trimming the pre-, and post-recording of the OBS video.
