Subject: [PATCH] Added HASS_STATE to command STATE

The command STATE has a secondary mqtt message in the case that SETOPTION59 is 1
This adds a HASS_STATE mqtt message if HomeAssistant discovery is enabled.

This is useful for syncing HomeAssistant with all the states of a Tasmota device when HA is restarted.
The actual automation for HA explained in the wiki will also make use of this new message.
