Move MeshReader into filamesh namespace.

This class will not extend well to glTF so this cordons it off into the
filamesh namespace, which is an already-existing namespace that we use
for the things related to the filamesh file format.

For glTF we might create a new library with its own MeshReader so
this will mitigate confusion.
