Demos (both for this and fingerpose) have issues

While the keypoints on screen are properly positioned, it will often misrecognize the curls of the fingers (for both of my hands being in an identical pose, one will say no curl and the other half curl)

Also can't report on fingerpose, the top of the README says it supports multiple hands while somewhere closer to the end it says it only supports one at a time, so which is it?
