[vgonkivs]

This PR removes the base64 flag and its related functionality as it was completely unused. Additionally, it changes the return type of the commitment to its hex representation.

Have you synced w @jcstein about this?
I think we need to remove it in docs as well

[vgonkivs]

I've discussed this change with him. But we haven't agreed on removing the flag and I think as we allow now only hexed namespace and commitment it won't have much sense in keeping base64 flag. For the commitment, I think it makes sense to keep all fields consistent.
