 After #3723 is completed, authorities will list the bandwidth file headers
 in their votes.
 After #21377 is completed, they will make bandwidth files available at a
 standard URL.

 But if we want to cryptographically verify the exact bandwidth file that
 was used in a vote, we need to put a hash of the file in the vote. Let's
 do it in an extensible way:

 bandwidth-file hash-algo base64(hash(bandwidth-file-content))
