[REG]: Introduce feature files addition to registry

[synchon]

Enable users to add features to registry like so:

$ junifer registry add [junifer-yaml] --registry [registry-uri-or-path]

This should add the feature file (HDF5), the Junifer computation file (YAML) and its corresponding metadata file (YAML) to the specified registry dataset. If the Junifer YAML file contains multiple features, all features should be added to the registry, each with their own files. The metadata file should be generated automatically based on the information in the Junifer YAML file as well as the computed feature file (e.g., size, shape, data type, etc.). If the registry is remote, the command should clone the dataset locally, add the files, and then push the changes back to the remote.
