Animation settings export/import for kepler component #263
Description
Currently the kepler component only supports a limited subset of animations the libraries are capable of supporting. Camera, resolution, layer animations, and filter animations could all be possible - but the user needs a way to configure them.
Let's consider adding a JSON template exporter for the user to fill in a custom animation, and an JSON importer to apply the animation.
This advanced mode could be enabled with a toggle on the video export component, which when enabled replaces the existing configuration UI with a JSON editor and/or a download/upload button.
