Load line art animation from .gpla file rather than from Blender directly

[DJLevel3]

Still working on polish and performance, but this works! I need to fix the exporter as well (find it here) which is why this is a draft.

Thanks so much for making this, overall it looks great!! Haven't actually run the code yet, and aware you are looking to make it polished and improve performance so will hold off on a full review until later, but just my initial thoughts :)

[DJLevel3]

I've made all the requested changes that I deem feasible for now, I still need to add some other functionality so this will remain a draft for the time being.

Fixes #127

Fixes #134

I'm pretty sure this is release ready! I have made all the changes I intended to make and I have fixed some bugs that I found, so I'm marking this as ready for review!

[jameshball]

Thanks again so much for all the changes! Sorry that the code review has gotten a bit stricter since the old osci-render days 😅 Keen to keep it easy to add new features :)

Hmm, Codacy is failing it for issues that I don't think are actually issues. It seems that it hasn't realized that the "HIDDEN" does actually do something properly when running in Blender, and that "*.gpla" is the file extension.

Thanks again!! I've fixed a few bugs with it - please can you do the following last few changes:

• Change any variable names/strings/ids etc. for MIDI sync to BPM sync (as discussed on Discord)
• Update the name of 'framerate' to:
  • 'Frames per second' when BPM sync is disabled
  • 'Frames per beat' when BPM sync is enabled
• Add tooltips to Animate, BPM Sync, FPS/FPB, and Offset labels/buttons to explain what they do
  • There are plenty of examples of how to do this in the codebase, but reach out if you need help!
• Do a final test
  • Particularly to make sure that the original Blender implementation is still working fine
  • Also to make sure that there is no weird behaviour around line saving that you spotted before
  • Test both standalone and VST

[DJLevel3]

All looks pretty good except for this one strange extra modulo that doesn't appear to be necessary. I'll compile and test momentarily.

[DJLevel3]

All works as expected, but I'm going to change one thing that causes unexpected behavior: I'm going to change the fallback BPM to 60 so that ticking the BPM sync box in the standalone doesn't double the speed of the animation.

[DJLevel3]

Oops I have to test one more thing, 1 sec

[DJLevel3]

The line art's strange behavior is also not occurring, so I think all is good!

[jameshball]

All good to go! Just needs a little bit of documentation and we're good to release :)
