* chore(lib/cli): one video per slide As titled, this PR changes how Manim Slides used to work by only storing one video file per slide. Previously, a slide would store all animations that occur during the given slide. Up to now, the only "advantage" of this was that it would allow the user to know which animation is played. But, at the cost of a very complex logic in present, just especially for reversed slides. On top of top, all converter actually need to concatenate the animations from each slide into one, so it is now performed at rendering time. To migrate from previous Manim Slides versions, the best is the render the slides again, using `manim render` or `manimgl render`. Currently, it is not possible to start at a given animation anymore. However, if wanted, I may re-implement this, but this would require to change the config file again. * fix(ci): trying to fix tests * chore(test): renaming files * chore(docs): remove old line from changelog * fix(docs): typo * fix(ci): manimgl and smarter comparison * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com>
