Added note to README about console support

This is mentioned in each of the respective board files' READMEs because the limitation only exists within those files (the library itself doesn't care what you're connecting to). But it doesn't hurt to mention it up front here, since it's all one system at the end of the day.

+Please be aware that none of the currently available board packages support connecting to the console itself. Genuine controllers use a dedicated hardware security chip that handshakes with the console. Arduinos do not have this chip, and its security method has not been (openly) broken.
