feat!: limit protocol streams per-connection (#1255)

Browse Source 
* feat: limit protocol streams per-connection

Uses the `maxInboundStreams` and `maxOutboundStreams` of the `registrar.handle`
opts to limit the number of concurrent streams open on each connection
on a per-protocol basis.

Both values default to 1 so some tuning will be necessary to set
appropriate values for some protocols.

* chore: make error codes consistent

* chore: fix up examples
