Replace hf models with dummies

[javiermtorres]

All modes that were previously downloaded from HF have been substituted with the dummy models. Dummy model generation works fine through the create_dummy_model-py (yet to be properly packaged as a runnable script), but the outputs are now part of the repo, so there is no need for additional generation. cargo test should work out of the box.
