Wrong componentType (too many vertices for uint8)

Hello,

In this file [0], the componentType of the indices accessor seems to be wrong.

Not sure how this file was created, but it is coming from Google 3D Tiles (so, Draco is also from google, so I hope you will be able to retrieve the right team)

The file has 314 vertices, so indices can't be stored on uint8 / componentType 5121
