Greg Laabs 930e475905 Const and logging cleanup, addition of is_cleaning and is_charging
All sucks vocabulary is now defined up-front in consts, so that library users can import those const instead of hard-coding them.

is_cleaning and is_charging properties were added to VacBot, avoiding library users to have to understand which vacuum statuses mean active cleaning.

All logging has been moved to instantiated loggers using the module's namespace, as is recommended by the Python docs.
