Released old code as library, made some refactoring
Usage example:

const inputPacket = [
243,2,38,0,12,40,105,0,0,0,1,23,
105,0,1,39,58,20,105,0,0,0,0,39,
111,1,24,102,0,0,0,0,25,102,65,
32,0,0,26,102,0,0,0,0,27,102,0,
0,0,0,28,102,0,0,0,0,29,102,0,0,
0,0,30,102,63,128,0,0,125,111,0
];

// @returns string
const packetType = KPD.typeOf(inputPacket);

// @returns decoded object
const data = KPD.decode(inputPacket);

// @returns array of bytes
const outputPacket = KPD.encode(data);
