examples: New lorawan basic-demo example

[ofauchon]

"basic-demo" is an example application for connecting a Lorawan Network. It's written to be as simple as possible so you can easily reuse it.

All the code shared between examples had been moved in a common package.

I think that perhaps a more bare bones rx-type example might be more useful than another console style application. Something that joins, then creates some periodic sensor readings maybe?

There was something wrong with DevNounce encoding/endianness. Fixed in this branch, but the code needs review ...

Anyways, Join and Uplinks are working with this PR. Please give a try . Thx
