A way to use mipmaps from Blender models

[mgsx-dev]

not an issue with the library itself, it handles all sampler configurations including mipmaps and then auto mipmap generation.
The issue come from blender and blender GLTF exporter which don't have options for mipmaps.
For these use cases, it could be nice to allow user code to force/override it at loading time.
It could be a loader option which would be global for all models loaded with this loader. This way, users could load some models with or without this option in order to have fine grain control.
