Fully implement the TP-Link Smart Home Protocol

[mweinelt]

Existing commands are referenced here: https://github.com/softScheck/tplink-smartplug/blob/master/tplink-smarthome-commands.txt

We should try and implement the existing ones with a sane documentation of input values, which might be a bit difficult when it comes to things like setting the timezone.

Some more API is implemented in #11. The case of timezone is unclear, but from looks of it they have a a hard-coded array of possible values + offset for those (as returned by get_timezone()), but set_timezone() itself is the setter for time() where index indicates the selected timezone. There seem to be no separate set_time() there.

We are closing this repository for new changes in favor of a new, asyncio-enabled continuation project: https://github.com/python-kasa/python-kasa

If the issue is still present in the new project, please feel free to open an issue there, thanks!
