Generate CBD process diagram(s) to add to Threshold Docs

These kind of diagram(s) for CBD help to clarify the process. Analogous to what we did for PRE.

This is excellent. The representation of DKG really captures what's going on. Couple small things:

• If we could somehow crowbar in a 'Data Producer' it would be a clearer starting point and also more symmetrical with the Recipient.
• We should convey that the encrypted data w/ conditions is 'brought' to the network nodes by the recipient, or I would be wondering whose action prompts this.
• This isn't important, but it is theoretically possible for the decryption frags to be handled by another cohort. Right now that looks impossible.

We Can always relabel Cohort of Nodes (m-of-n) to Nodes (m-of-n) if needed.

I'll attach the final svgs once we're done with review.
