Philipp von Weitershausen 66158ab2bf Make the RCTSRWebSocketDelegate protocol part of RCTWebSocketModule public
Summary:
This allows consumers to subclass and extend `RCTWebSocketModule` and make use of the `RCTSRWebSocketDelegate` methods.

The use case here is to do some pre-processing of WebSocket data before handing it off to JS. Consumers could that in the following way:

```

interface MyWebSocketModule : RCTWebSocketModule
end

implementation MyWebSocketModule

// Don't use RCT_EXPORT_MODULE macro for this so we replace the existing RCTWebSocketModule.
+ (NSString *)moduleName { return @"RCTWebSocketModule"; }

RCT_EXTERN_METHOD(connect:(NSURL *)URL socketID:(nonnull NSNumber *)socketID)
RCT_EXTERN_METHOD(send:(NSString *)message socketID:(nonnull NSNumber *)socketID)
RCT_EXTERN_METHOD(close:(nonnull NSNumber *)socketID)

- (void)webSocket:(RCTSRWebSocket *)webSocket didReceiveMessage:(id)message
{
  [super webSocket:webSocket didReceiveMessage:[DoSomethingWith message]];
}

end
```

... and then returning a `MyWebSocketModule` ins
