Correctly pad bytes with zero in hex conversion
When reading a secret in ascii or base32 format from the user, we perform a conversion of the potentially decoded string into hexadecimal bytes, because that is what libnitrokey expects. The format string we used in the conversion, however, did not account for padding with a leading zero for single digit results. E.g., the newline/line feed symbol '\n', which has a decimal value of 10 would result in the string 'a' being produced, whereas '0a' would be the correct result. This change corrects the format string to fix this problem.
