Major updates and fixes

Added availability topic in HA as V1 devices report state every
4 hours at most, and V2 devices report every 2 hours at most.
Added a state file that gets saved on shutdown and sensor reload.
This file saves the last seen timestamp and online state for each
sensor so that it has consistancy across reboots. Something to add
in the future is the shutdown timestamp, so that if the service is
down for a long time, it can just ignore the previous timestamps
instead of marking everything offline and having to wait for sensors
to individually report one by one to come back online.

Added timeout setting for sensors to configure a timeout per device
if desired. Otherwise it'll default to 4 hours for V2 devices and
8 hours for V1 and unknown devices. This is twice the max status
period to allow for one missed status update.

Also added a global availability topic that is set online when the
service is running. Both the global availability and the per device
availability must be set to online for a device to be available.

Switched mqtt connection method so it connects faster and availability
topics are sent after the connection is active rather than before.
This also allows the main thread to loop and check availability of
the sensors.

The main loop also checks communication with the dongle, by getting
the mac address, which allows us to close and reopen the dongle if
we lose communication with the device. This is an issue I've been
dealing with for a long time.

Fixed shutdown by sending the correct signal in the service file
and properly handling it in shutdown. Wait for dongle loop to finish
before closing the fd.

Updated logging. Set the sample logging conf to INFO instead of DEBUG
and updated log messages to primarily log mqtt messages/events, etc
at this level. Passing in LOGGER to the dongle class so logs from the
dongle show up in the log file.

Fix packet parsing to not throw away partial packets which can be
parsed correctly when the rest of the message is received.

Fix new device scan to add the device even if the additional calls
timeout, as long as we got a result from the scan.

Fix automatic device adding for already linked devices to default
the class to opening instead of None. This means even motion sensors
will be initially added as a contact sensor, but should get fixed when
the sensors.yaml configuration is updated.

-This file will store basic information about each sensor paired to the Wyse Sense Bridge. The entries can be modified to set the class type and sensor name as it will show in Home Assistant. Class types can be automatically filled for `opening`, `motion`, and `moisture`, depending on the type of sensor. Since this file can be automatically generated, Python may automatically quote the MACs or not depending on if they are fully numeric.
