Use aioharmony for remote.harmony platform (#19595)

* Use aioharmony for async

Use aioharmony to interact with Harmony hub. Due to this following improvements:
-) Setting of available state for entity
-) Automatic config update if configuration changes (including updating file containing config)
-) Allow using of device name instead of number
-) When sending command with repeat, nothing else will be able to put a IR command in between

* Requirements updated

* Version update for fix

* Mainly cleanup

* Update requirements

Updated requirements

* Fixed lint issue

* Small bump for aioharmony

Small version bump increase for aioharmony

* Updated based on review
