v0.0.18: Repo metadata, git tags, Keras mixin

Repository metadata (@julien-c)

The version v0.0.18 of the huggingface_hub includes tools to manage repository metadata. The following example reads metadata from a repository:

from huggingface_hub import Repository

repo = Repository("xxx", clone_from="yyy")
data = repo.repocard_metadata_load()

The following example completes that metadata before writing it to the repository locally.

data["license"] = "apache-2.0"
repo.repocard_metadata_save(data)

• Repo metadata load and save #339 (@julien-c)

Git tags (@AngledLuffa)

Tag management is now available! Add, check, delete tags locally or remotely directly from the Repository utility.

• Tags #323 (@AngledLuffa)

Revisited Keras support (@nateraw)

The Keras mixin has been revisited:

• It now saves models as SavedModel objects rather than .h5 files.
• It now offers methods that can be leveraged simply as a functional API, instead of having to use the Mixin as an actual mixin.
