updates

beta 3 - scheduled prompting uses interpolation between keyframes you make.

- unrats nest almost complete. Most nodes now run through a bus

- rearranged previews to the start of the flow, rearanged middle for my sanity.

- added combine masks to combine video masks into one mask. Lower vram but much less accurate.

- added custom masking preview to all custom mask areas.

- added custom mask mix with subject masks

- added masking connections everywhere to allow subject/background/faces/custom masks to be used anywhere.

- added line art from depth as an option with line masks.

- added video preview for numbered frames

- added background scroller option to make scrolling backgrounds. (testing)

- removed bg depth/line groups. Now just generated when you connect it. no prevews.

- remove/add to masks should be easier with the combine masks preview.

- tried to remove unneeded things to not confuse people.

- mask previews now show lineart of the masked area to display what the control net will be working off of.

- added repeat video for those small .gif files that are small number of frames and can be looped.
