Makie GUI

[emiwar]

Would be nice to have a Makie.jl GUI. It's technically possible to make CuArrays work directly with GLMakie so that no info is transferred back and forth between host and device, but not not sure if that's worthwhile to implement.

The GUI is currently unnecessarily slow. Especially with a large number of videos/cells (then the traces become huge). Should refactor the footprint script to instead use CUDA operations.

General todo-list for the GUI:

• [ ] Approximate a better solution to the graph-coloring problem
• [ ] Use GPU to construct the ROI viz
• [ ] Instead of showing all traces, allow users to click on cells to enable/disable their traces. This should also make more room.
• [ ] Make GUI run in it's own task so that it doesn't freeze when computing + make some kind of progress bar
• [ ] Make two modes of the video player: one that loads whole segments and one that just loads the a single frame directly from disk. This is important when jumping around a lot in a bigger-than-memory video.
• [ ] Improve playback speed by not sleeping 0.05s but instead keep track of time since last update and only sleep if that time is > 0.05s.
• [ ] Change x-axis of trace plot to time, and indicate segments/videos
• [ ] Fix zooming in on traces (limit the zooming).
• [ ] Menu for opening and loading videos.
• [ ] Menu for opening/saving results. (Plus option for auto-save).
