Remove bio_embeddings dependency

This release removes the dependency on bio_embeddings.
This speeds-up EAT-based inference via ProtT5 (now default embedder) and removes most of the dependencies.
There is still an BioEmbEmbedder class (currently unused) which shows how embeddings can be again computed via bio_embeddings for backward compatibility and more flexibility on use-cases.

First release of embedding-based annotation transfer (EAT)

This is the initial release for annotation transfer between proteins using embedding-based annotation transfer (EAT).
