Allow PSK instead of passphrase in WiFiSTA::begin

Browse Source 
In WPA protocol, the maximum length of the passphrases are 64 characters in order to distinguish them from the actual PSK who is 64 ASCII characters long, so in most systems if a 64 chars string is passed, it is assumed to be a PSK, otherwise is treated as a passphrase and is used to compute the PSK.
