[HOU-3213] Load EXR layer as a texture

[glacierise]

Would be great if we could specify EXR layer when we load texture. Would make managing multi channel texture much easier, baking and loading them.

Thanks!

Hey Hristo,

I've logged a request and we'll discuss this with the development team. I'll keep you posted.

Best regards!
