Fix/loramesh example (pycom#103)

cuca94 · Catalin Ioana · commit 60f2592ab6b8 · 2019-06-13T15:28:52.000+03:00
* fixed receive callback function rc_cb needs two parameters, the callback routine and the sockets which should be checked for incoming data (https://docs.pycom.io/firmwareapi/pycom/network/lora/pymesh.html#meshrxcbhandler-argument) without fixing this, the example will crash after connecting to the mesh network see forum entry: https://forum.pycom.io/topic/4912/loramesh-example-crashing-on-lopy4 * added copyright notes
