Report unavailable on temperature sensors when Hayward returns 255 degrees

Set temperature sensors to unavailable when Hayward returns 255 degrees. Hayward will return 255 when the panel is in service mode or is otherwise unavailable.

Fix unique issue when a pool doesn't have any sensors at the Backyard or Body of Water level

Fixed #29 where there were no sensors in the Backyard or Body-of-Water coming from Hayward.

Fixes for lights, translations, and documentation links.

Handle condition where V2 flag is not added from telemetry, but ColorLogic lights support brightness and speed. Related to issue #21.
Update integration documentation link to point to the custom repository instead of the default Home Assistant integration documentation.
Update the translations file to properly show the prompts for config flow setup and config dialogues to finally properly fix #11.

Handle relays that aren't part of a BOW. Continue to try to stabilize timeouts.

Add support for Relays that aren't part of a Body of Water in the OmniLogic config - thanks @lurgh

Extend timeouts to 30 seconds for calls to OmniLogic, extend standard polling time to 30 seconds to try to help with the number of timeouts coming from Hayward.

Handle login errors from API, retain last data on timeout

Handle login errors from the API in case you change passwords on the Hayward app. (Note: if your credentials change you'll need to delete and reinstall the integration. There is currently no way to change username or password once installed).

Retain the last telemetry data for up to 10 consecutive timeout errors from the Hayward API to try to prevent sensors/switches from going "unavailable" when Hayward doesn't respond (which happens too frequently).

Fix duplicated pumps between bodies of water.

Bump API version to 0.4.8 to fix issue where pumps were duplicated between bodies of water (#3)
