I add mainly two functions and one small function

1. Jump to specific slices of image: No need to label from first images always, users are able to manual choose which slice of image to label from.
2. Paint and eraser function: Model not always work well, user are able to use paint and eraser to add or erase mask.
3. Visualize current slice and it's ID allow user to know which images they are labeling.
   Thanks!
