2.0.0 Beta 1

Initial release compatible with AMPHP v3.

As with other libraries compatible with AMPHP v3, most cases of parameters or returns of Promise<ResolutionType> have been replaced with ResolutionType.

• Removed the Options object. Settings that were set using properties on the Options object are now parameters to client factories in the websocket-client and websocket-server libraries or the HeartbeatQueue and RateLimiter interfaces
• Added HeartbeatQueue and RateLimiter interfaces with implementations DefaultHeartbeatQueue and DefaultRateLimiter – these objects replace some of the functionality that was only contained within Rfc6455Client and controlled via Options
• Opcode is now an enum
• Added Websocket as a prefix to several classes:
  • Client renamed to WebsocketClient
  • ClientMetadata renamed to WebsocketClientMetadata
  • Message renamed to WebsocketMessage
• WebsocketClient now extends Amp\Closable
  • isConnected() method replaced with isClosed()
• WebsocketClient::receive() now supports cancellation. Cancelled receives do not discard a message, a subsequent call to receive() will still return the next message received from the client
• Closures provided to WebsocketClient::onClose() are provided an instance of WebsocketClientMetadata instead of the client object, close code, and reason. The code and reason are available on the metadata object.
