Vertex and Normal data mixed up in Unity 2018.2 AssetBundles

[rogangriffin]

When I use the export.py functions on Unity 2018.2 AssetBundles, the vertices and normals get mixed up in the arrays. Vertices array looks like 1 vertex Vector3, then 3 normal Vector3s, then 1 vertex Vector3, then 3 normal Vectors, etc.
Normals then has vertex position data mixed in.
I guess their format changed. Attaching an AssetBundle (simple cube) from 2018.2.

Sorry about the whitespace changes.
I am going to be converting a ton of Unity 2018 assets with this so I will update as I find more issues.
