Subject: [PATCH] Prevent calling impl.close() more than once

There was a possibility of getting succesive close() calls within process() from both ondata() https://github.com/soywiz/haxe-ws/blob/32b81123e4545742c0907473ad1690518cbf299d/src/haxe/net/impl/SocketSys.hx#L109 (via WebSocketGeneric's handleData()) and a direct call in https://github.com/soywiz/haxe-ws/blob/32b81123e4545742c0907473ad1690518cbf299d/src/haxe/net/impl/SocketSys.hx#L114. Which unsurprisingly led to Error,std@socket_close
