As discovered in #102, I'm not sure why but passing in a `Texture` to `RasterLayer` works while passing down bare `TextureProps` _do not_. Because of this, we pass in `device` into the `loadTexture` so that the user callback can call `device.createTexture` and we change the type hint of the callback so it returns `Texture`. Prep for #109

We no longer need to apply the colormap and convert to RGBA on CPU. The colormap is added to the GPU as a texture and then the colormap is applied there. This means it's faster and uses less CPU memory since we don't have to expand to RGBA on CPU.
