[enocean] Improved device discovery and added SMACK capability (#10157)

 * Added SMACK teach in
 * Teached in devices can be teach out on a repeated teach in
 * Improved detection of RPS devices, device types can be better distinguished now
 * Bugfixes for discovery fallback to GenericThings
 * Responses to message requests are send automatically now, no need for linking SEND_COMMAND channel

Fixes #10156

 If the actuator supports UTE teach-in, the corresponding thing can be created and paired automatically.
 First you have to **start the discovery scan for a gateway**.
 Then press the teach-in button of the actuator.
-If the EEP of the actuator is known, the binding sends an UTE teach-in response with a new SenderId and creates a new thing with its channels. 
+If the EEP of the actuator is known, the binding sends an UTE teach-in response with a new SenderId and creates a new thing with its channels.
+
+This binding supports so called smart acknowlegde (SMACK) devices too.
+Before you can pair a SMACK device you have to configure your gateway bridge as a SMACK postmaster.
+If this option is enabled you can pair up to 20 SMACK devices with your gateway.
+
+Communication between your gateway and a SMACK device is handled through mailboxes.
+A mailbox is created for each paired SMACK device and deleted after teach out.
+You can see the paired SMACK devices and their mailbox index in the gateway properties.
+SMACK devices send periodically status updates followed by a response request.
+Whenever such a request is received a `requestAnswer` event is triggered for channel `statusRequestEvent`.
+Afterwards you have 100ms time to recalculate your items states and update them.
+A message with the updated item states is built, put into the corresponding mailbox and automatically sent upon request of the device.
+Pairing and unpairing can be done through a discovery scan.
+The corresponding thing of an unpaired device gets disabled, you have to delete it manually if you want to.
 
 If the actuator does not support UTE teach-ins, you have to create, configure and choose the right EEP of the thing manually.
 It is important to link the teach-in channel of this thing to a switch item.

 Items linked to bi-directional actuators (actuator sends status messages back) should always disable the `autoupdate`.
 This is especially true for Eltako rollershutter, as their position is calculated out of the current position and the moving time.
