* Update I/O Linc Documentation
The I/O Linc has a feature to match or invert the status of the contact with its control messages. The binding was written expecting the messages to be inverted. This is the opposite of how insteon recommends setting up the garage kit, and not described well by the original "Note" at the bottom of the section. Updated the instructions to specify the input is OFF when linking, and changed the note to better describe what happens if you don't. All based off of my own experience with the sensor: https://community.openhab.org/t/insteon-io-linc-garage-door-contact-slow-update/141469
