Add config flow and restore_light_state to ISY994

[shbatm]

Proposed change

Update method for adding the integration to include using the new config flow via the integrations page.

Add the restore_light_state parameter: The ISY994 integration now includes a restore_light_state option. In 0.109.0, a change was made to restore a light's brightness to the previous state when turned on with no brightness parameter. This was, in part, to fix an issue where the light would turn on to full brightness when no parameters were given, regardless of the physical device's On Level brightness setting. Using the On Level is now supported and this is being made the default behavior to keep it the same as turning on the physical switch. To keep the current behavior and use Home Assistant's last brightness, set the restore_light_state is set to True or enable the option in the new config flow options.
