* 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
