Add blebox binary_sensor platform (#79535)

* Add binary_sensor platform, with test.

* Applied suggestions by @epenet

* refactor: as @epenet suggested, passing entity_description to init

* Update homeassistant/components/blebox/binary_sensor.py

@epenet suggestion, moved refactored logic of create_blebox_entities into BleBoxBinarySensorEntity init

Co-authored-by: epenet <6771947+epenet@users.noreply.github.com>

* refactor: as @epenet class selector and entity creation moved to binary_sensor

* refactor: list comprehension in entity list setup in binary sensor

* Update homeassistant/components/blebox/binary_sensor.py
