The option to capture frames in WebP/JPEG XL format

[Helspank]

I have a lot of issues to go through, so in order to make it easier for me to help you, I ask that you please try these things first

• [X] Check out all the menus and keyboard shortcuts. Maybe the feature already exists?
• [X] Try with the newest version from GitHub
• [X] Read the documentation and FAQ, Known issues, Troubleshooting to see if the feature already exists
• [X] See if someone already suggested this under Issues or Discussions

Description

This would be particularly useful when extracting a segment as a sequence of image files, it would save a lot of disk space.

• [x] For HTML5 image capture, webp support can be easily added (as it is supported in chromium).
• JPEGXL is not supported in chromium afaik.
• [ ] For ffmpeg support, both can be supported, but need to add corresponding libs to the ffmpeg build: https://github.com/mifi/ffmpeg-build-script
