feat: ✨ FILM interpolation nodes

[melMass]

This just adds a few nodes

Note
Something wen't wrong in the last PR and the submodules where not properly initialised... This PR also fixes that

• Load FILM Model: Loads a FILM model, the download_model script has been updated to download (L1, Style and VGG)

• Film Interpolation: The main node that does all the processing. This is quite heavy and memory heavy, there is probably some optimizations possible. <- This is just when using tensorflow cpu, it's like 100x slower

• Export To ProRes4444: Experimental node that uses ffmpeg stdin to pipe comfy tensor images to a video file.

• Concat Images: This is probably somewhere builtin but I could not find, it allows to merge IMAGE input of variant batch size but with the same shape otherwise (H,W,C should match)

Todo

• test in isolation (comfy-embed) to query the minimum required dependencies.

Example:

Using 2 frames, with interpolate = 5 -> result in 33 interpolated frames, played here at 20fps

Merging as it's already growing too much and the base idea of the PR is there
