====== Fetching panid part 2 ======

For some reason, using the at command mode (sending +++) at the beginning failed recently with the production xbee when I tried it. I wanted to fetch the panid from the production xbee to validate what it was. 

This script works though, which uses the digi python library and I believe directly sends/parses frames instead of relying on text.
