* Allow mask batches

This allows LatentCompositeMasked -node to work with AnimateDiff. I tried to keep old functionality too, unsure if it's correct, but both single mask and batch of masks seems to work with this change.

* Update nodes_mask.py

This node takes a list of sigmas and a sampler object as input.

This lets people easily implement custom schedulers and samplers as nodes.

More nodes will be added to it in the future.

Remove MAT because it's unused and the license is incompatible with GPL.
