wifi service: add utility to check printability
When logging data, it's useful to know whether or not
the data is plain ASCII. (If so, we can print the
data raw. Otherwise, we need to base64 encode the data.)
To meet this need: add a utility method to check if a byte
buffer contains (only) printable ASCII.
