this commit includes
-a stream-optimized node for detecting facial landmarks
-node for drawing the mesh on an image from the landmark data
-node for creating masks from the landmark data
This commit migrates the Feature Bank node, originally implemented by @RUFFY-369
on [RUFFY-369/ComfyUI-FeatureBank](https://github.com/RUFFY-369/ComfyUI-FeatureBank),
to the new streampack.
The Feature Bank node is a ComfyUI-native implementation of the method proposed in
[Looking Backward: Streaming Video-to-Video Translation with Feature Banks](https://arxiv.org/abs/2405.15757)
by Liang et al. It enhances the stream diffusion model by providing information from
previous frames, thereby improving temporal consistency and reducing flickering.
