clayjohn d1043a5f93 Enhance checks and user experience around tangents. 
Ensure `ensure_tangents` option actually creates tangent array. Even if it is just a dummy array.

Allow mesh to generate its own tangents when using compression. This allows users to compress meshes without tangents.

Warn users if they are trying to read from tangents without providing tangents.
