[Accessory] WS2 Individual Probe on Shelf Now

We realize that some users who have purchased the ws2 will sometimes want to add the need for some probes, and it would obviously be foolish to re-purchase a controller.

We have now added a separate probe offering.

• Each WS2 controller supports up to 4 probes.

Please note that they do not apply to the WS1, which does not have an expansion port.
