Display and filter e164.country_code and e164.identification_code as decimal instead of hexadecimal, as that is more natural. E.g. Use 'e164.country_code == 61' instead of 'e164.country_code == 0x61' to match Australia (+61...) If the country_code or identification_code contain BCD digits > 9 add an expert info warning. Required modifying the various prefix to description value_string arrays from hex to decimal constants, and converting the decoded BCD from hex to decimal before adding to the proto tree.
