Message:

Add support for the wip soju.im/read capability and READ command

READ lets downstream clients share information between each other about
what messages have been read by other downstreams.

Each target/entity has an optional corresponding read receipt, which is
stored as a timestamp.

• When a downstream sends: READ #chan timestamp=2020-01-01T01:23:45.000Z the read receipt for that target is set to that date
• soju sends READ to downstreams:
  • on JOIN, if the client uses the soju.im/read capability
  • when the read receipt timestamp is set by any downstream

The read receipt date is clamped by the previous receipt date and the
current time.
