fix #269 see below

/**
 * Generate a short suffix used to disambiguate channels that might have the same "name" entered by the human but different PSKs.
 * The ideas is that the PSK changing should be visible to the user so that they see they probably messed up and that's why they
their nodes
 * aren't talking to each other.
 *
 * This string is of the form "#name-XY".
 *
 * Where X is a letter from A to Z (base26), and formed by xoring all the bytes of the PSK together.
 * Y is not yet used but should eventually indicate 'speed/range' of the link
 *
 * This function will also need to be implemented in GUI apps that talk to the radio.
 *
