Support for texture array / compressed texture array in MeshBasicMaterial and MeshStandardMaterial by index

[A2H2]

Description

Currently its not possible to create material using single texture from regular or compressed texture array.

Solution

When creating material, I would like to specify concrete texture from texture array by index / layer / depth so given texture is used. Also I would be able to change index to change texture easily in code.

Alternatives

Currently to my understanding only custom shader can work with texture arrays.

Additional context

Currently I am loading lot of texture from ktx2 container which contains lot of compressed textures. I would like to use existing MeshBasicMaterial so I can benefit from its features like lights.
