General cleanups all around (janitoring) (#63)

* Move tests to device-type specific test files to make improvements more approachable

* protocol: remove the port parameter from query, as there are no other known ports, fix docstrings

* Revise docstrings, remove superfluous information and remove unused methods ({set,get_icon} and set_time)

* cli: indent device output to make it more easily readable when having multiple devices

* remove adjust flake8 ignores (we have no setup.py anymore)

* pyproject: include cli tool to coverage, add config for interrogate (docstring coverage)

* bulb: raise exception on color_temp error cases instead of returning zero values

* improve bulb tests, simplify conftest

* strip: rename plugs property to children and move it to smartdevice
