v0.5.0

Changed

• Connection identifier is now included in the error log if we can't forward a
  seqno request.
• Garbage collection time for source entries has been increased from 5 to 30 minutes
  for now.
• The router implementation has been changed to use regular locks instead of an
  always readable concurrency primitive for all but the actual routing table. This
  should reduce the memory consumption a bit.
• Public key and shared secret for a destination are now saved on the router, instead
  of maintaining a separate mapping for them. This slightly reduces memory consumption
  of the router, and ensures stale data is properly cleaned up when all routes to
  a subnet are removed.
• Hello packets now set the interval in which the next Hello will be sent properly
  in centiseconds.
• IHU packets now set the interval properly in centiseconds.
• IHU packets now set an RX cost. For now this is the link cost, in the future
  this will be set properly.
• Route expiration time is now calculated from the interval received in updates.
• Ip address derivation from public keys now uses the blake3 hash algorithm.

Fixed

• Don't try to forward seqno requests to a peer if we know its connection is dead.
