Texture should support integer formats.

[comradez]

Is your feature request related to a problem? Please describe. I have an 8-bit integer array and I want to set it as the texture. However, I have to convert it to float format first, which is a great overhead.

Describe the solution you'd like Add integer support for raw textures.

Describe alternatives you've considered Add integer array versions of LoadTextureFromArrayRaw, and add additional supports above it.

Hi! We plan on opening up the texture formats very soon. The biggest issue was handling differences between platforms but we now have most of what we need to do so.
