jimboca 6115d96c39 Add support for HS300 power strip (#137)
* discover runs, prints on since of device 0

* added preliminary support for HS300

* forgot to add smartdevice to commit

* added index to CLI

* clean up dirty code

* added fake sysinfo_hs300

* changed device alias to match MAC

* #131 Move _id_to_index into smartstrip so everyone can pass index

* Update pyHS100/discover.py

Co-Authored-By: jimboca <jimboca3@gmail.com>

* refactoring to deduplicate code between smarplug and smartstrip

* fixing CI failures for devices without children

* incorporating feedback from pull request.

* fixing hound violation

* changed internal store from list of dicts to dict

* changed other methods to dictionary store as well

* removed unused optional type from imports

* changed plugs to Dict, remove redundant sys_info calls

* added more functionality for smart strip, added smart strip tests

* updated FakeTransportProtocol for devices with children

* corrected hound violations

* add click-datetime
