  1. Import the second UV map if present in glTF files. 

    Conventionally, the second UV map (`TEXCOORD1`, `UV1`) is used for
lightmap UVs. This commit allows Bevy to import them, so that a custom
shader that applies lightmaps can use those UVs if desired.

Note that this doesn't actually apply lightmaps to Bevy meshes; that
will be a followup. It does, however, open the door to future Bevy
plugins that implement baked global illumination.
