COCO-Hands & TV-Hands annotations out of bounds for images.

[BrentZ-1849203]

Some annotations in the datasets show numbers that are out of bounds for the given image. It's possible that the code these datasets are used with handle these cases but some other implementations might not which could lead to errors. It might be useful to change all out-of-range numbers to be the max/min size of the image.

Thanks for making these datasets public since they are very useful and well made.
