------------------------------+--------------------------------
'''The idea:''' Consensus documents are compressed with zlib, but nobody
has to compress any given consensus more than once. Therefore, we can
safely use more CPU compressing them, and save bandwidth on consensus
downloads by switching to something else instead of zlib for consensuses.
This same analysis also applies to consensus diffs.
For this ticket, we should look at the code complexity and potential
bandwidth savings here, and decide whether they are worth it.
