Adds support for Kandinsky5 -family video and image models.

Model code is refactored to be more in line with models I'm used to work with, and optimized for lower peak VRAM consumption.

I took the liberty of including RoPE and FFN chunking I've been testing, as it had rather big benefits at the higher input sizes these models support, namely the 241 frames for the 10s models, chunking dropped peak VRAM usage by:

  • At 768x521: ~15%
  • At 1280x768 for 241 frames: ~33%

Speed differences were within margin of error. Chunking is currently enabled based on sequence length.
