GSM 7 Bit Decoder
// This decoder is based on this answer https://stackoverflow.com/a/21115816
// It's not perfect, e.g. it does not accommodate the extended alphabet.
//
// Solution from SO answer paraphrased below:
//
// For input: C7F7FBCC2E03
// 1) Form tuples for hex numbers and reverse
// -> 03-2E-CC-FB-F7-C7
// 2) Convert hex to 8-bit binary octets
// -> 00000011-00101110-11001100-11111011-11110111-11000111
