Subscriber use only.

Promiscous.global_key            # get the global version key
Promiscous.global_version        # get the global version
Promiscous.global_version!       # increment the global version
Promiscous.global_version = 123  # set the global version
Recovery mode (also used for an initial sync)

When using `promiscuous subscribe --recovery` the worker will detect

yell for skipped messages.
