c91c1043a0 Fixed issue where JS would change subscription subject 
This would cause issues during a reconnect

cfef5e6c50 Reworked PullSubscribe implementation 
Use a SyncSubscription instead. The only visible change from the
user is that calling Fetch() after Unsubscribe() returns ErrBadSubscription
instead of timeout or context deadline exceeded, which makes more
sense to me. This is the only test that I had to tweak.

90f007b828 Ordered Consumers 
This introduces ordered consumers. They are a convenience over ephemeral, no ack, no redelivery, only deliver things in strict order setups.
We have the swap out when we detect gaps and change out the underlying sub and JetStream consumer, and we process the heartbeats as well, detecting gaps at the end or if a stream or consumer is pulled out from underneath of us.

077cf107c9 Make Durable mandatory for PullSubscribe 
nats.Durable is a SubOpt that may be passed to PullSubscribe or other
methods. If a durable name isn't passed to PullSubscribe, then we return
a runtime error.

Instead of returning a runtime error for this case, this change updates
the PullSubscribe method to require a durable name parameter.
