gsm0808: Add utils for AoIP Transport Layer Address
The planned support for true A over IP requires the encoding and
decoding of a so called "AoIP Transport Layer Address" element.
This commt adds parsing functionality and tests for the element
mentioned above, however, it is not yet actively used.
