ZeroMQException(22): EINVAL when setting the SUB socket option.

[Beaverking]

I have the SUB socket:
subscribeSocket = m_context.createSocket(SocketType.sub);
I then try to set the "conflate" option to it:
subscribeSocket.setOption(ZMQ_CONFLATE, "1");
But I get this exception:

ZeroMQException(22): EINVAL

0      _checkErrorCode (package:dartzmq/src/exception.dart:56:5) exception.dart:56
#1      _checkReturnCode (package:dartzmq/src/exception.dart:49:5) exception.dart:49
#2      ZBaseSocket.setOption (package:dartzmq/src/socket.dart:244:5) socket.dart:24

Some other functions in the socket.dart specify that I should use the Z85 encoding for the input string. Is it also the case here?
This is on Android BTW.

It seems that the value (string) is not expected here. Looking at the documentation a boolean is expected. We might need a different way of handling this.

@Beaverking can you try the latest dev branch?
