Adds a new public add_to_hash_buffer function to the transcript that adds elements to the current_round_data buffer without adding them to the proof_data. This will enable us to hash things without explicitly including it in the proof like vk data that needs to be Fiat-Shamired but doesn't need to be sent in the proof.

renamed because this is adding data to the proof? if so then yeah, why not

LG but I think the comments/naming could be improved

Can you update this description to mention that this doesn't implicitly add to the proof?

Any reason why a more explicit name like add_to_hash_buffer() wouldn't be appropriate here?
