// Demonstrating the use together with Long.js (https://github.com/dcodeIO/Long.js)
//
// Packing a long requires the input of a 2 part array containing the [low, high] bits
// of the specific long value.
// Unpacking a long results in a 3 part array containing [low, high, unsigned] bits and flag.
// The decoded value can be applied directly to Long.fromBits()
//
// Test number u            228290380562207 (BE: 0x00, 0x00, 0xcf, 0xa0, 0xff, 0x09, 0xff, 0x1f)
//                                          (LE: 0x1f, 0xff, 0x09, 0xff, 0xa0, 0xcf, 0x00, 0x00)
// Test number s           -228290380562207 (BE: 0xff, 0xff, 0x30, 0x5f, 0x00, 0xf6, 0x00, 0xe1)
