The distinction is made between files cached from the Hub and assets. Files from the
Hub are cached in a git-aware manner and entirely managed by `huggingface_hub`. See
[related documentation](https://huggingface.co/docs/huggingface_hub/how-to-cache).
All other files that a downstream library caches are considered to be "assets"
(files downloaded from external sources, extracted from a .tar archive, preprocessed
for training,...).
