Add new client tool (#42)

* Add new client tool

After installing the package pyhs100 command-line tool can be used
to control the plug.

See --help for its usage, most of the features for plugs are implemented,
some of the shared functionality works for bulbs too.

* Add discover command

* Delete old examples, the cli works as an example well enough
