Input: imagis - clarify the usage of protocol_b
protocol_b is a property, which tells Imagis panel to use a different format for coordinates. IST30XXC series is known for using protocol B, while the other series aren't. Note this could be confusing, unlike the model name implies. Adjust the usage of protocol_b to avoid confusion.
