Also, a close code of 1000 will now warn as unknown.
Always check for a session id before resuming, and fall back to a reidentify if the resume fails. In all cases, wait 1 second after resuming fails in order to not spam log messages.

This PR refactors how the gateway connection being closed gets handled, and also reworks how resuming is performed. If a resume fails, or if the session id is invalid/doesn't exist, the shard will fall back to restart + reidentify after a 1 second delay. This behavior was only present in some circumstances before.
Also, cleaned up the loop in
ShardRunner::runby adding aShardAction::Dispatchvariant, since event dispatch was already mutually exclusive to hearbeating, identifying, and restarting. The overall effect is less interleaving of control flow.Plus, removed the
Shard::{reconnect, reset}functions as they were unused.A notable change is that 4006 is no longer considered a valid close code as it is undocumented, and neither is 1000, which tungstenite assigns as
Normalor "clean". We should stick to the table of close codes provided by Discord.
