snac: update to 2.52. Changes:

Posts that were liked or boosted can now be unliked and unboosted.

Outgoing message timeouts are no longer hardcoded and can be
configured (see `snac(8)` for more information).

Fixed a bug that caused some incorrect unfollows under special
conditions (with shared inboxes enabled and users from the same
instance that follow each other, the internal message distributor
was confused).

Mastodon API: Added support for lists.

Added a header to avoid over-zealous caching in some browsers
(contributed by louis77).

Added support for running and federating inside hidden networks
like Tor, I2P or Loki (contributed by iwojima).

Fixed an error processing polls coming from Pleroma instances.
