`faceMesh` lips missing `keypoint` 291

[jackbdu]

Hi all, I noticed in the faceMesh parts example, there is a missing keypoint (291 on the mesh_map). See this sketch with keypoint 291 drawn in red. The same issue is present in the original tfjs demo so I'm not sure what we should do. Would it make sense to manually add this keypoint in ml5 for the time being (until it's fixed in tfjs)?

@jackbdu thank you for submitting this issue! We certainly should open an issue with tfjs about this. In the meantime, it should be simple to fix this within ml5 temporarily.

Thank you @jackbdu for reporting and @ziyuan-linn for adding support! How does this affect the documentation? cc @B2xx who is working on this. Does anyone want to volunteer to open the tf.js issue?

@ziyuan-linn Thank you for addressing this so quickly!

@shiffman I went ahead and opened an issue about this on tfjs repo.
