Changed the variable length of wifi_psk

[tobi-sys]

Correct the length of the variable wifi_psk

WiFi PSK can be 256 bits = 32 Bytes and can be represented by a 64 character long hexadecimal string
The size of the variable must be 65 bytes to hold the string and the trailing \0

This change would need to be made in the protobufs repo

[garthvh]

Sorry, missed the repo, was looking at another issue. Is 1 byte more enough to save a 64 byte password? We probably can’t go much bigger.

currently 63 character long key can be stored in the variable
meshtastic --set network.wifi_psk 123456789A123456789B123456789C123456789D123456789E123456789F123

Completed getting preferences
a one byte longer variable (so 65 bytes) can hold the possible 64 character long PSK and the string termination (\0)
