This release adds a `value()` operator for looking up a characteristic value:
python
a = Accessories.from_file("tests/fixtures/hue_bridge.json").aid(6623462389072572)
buttons = a.services.filter(
service_type=ServicesTypes.STATELESS_PROGRAMMABLE_SWITCH,
order_by=(CharacteristicsTypes.SERVICE_LABEL_INDEX, CharacteristicsTypes.NAME),
)
assert buttons[0].value(CharacteristicsTypes.SERVICE_LABEL_INDEX) == 1
* Adds an `order_by` kwarg to `services.filter` for returning the list ordered one or more child characteristics (see above example)
* Adds a `InputEventValues` enum.
