function hexToAb2(hexString) {
    return new Uint8Array(hexString.match(/[\da-f]{2}/gi).map((h) => parseInt(h, 16)))
}

function hexPairsToAb(string) {
    let arrayBuffer = new Uint8Array(Math.ceil(string.length / 2));
    for (let i = 0; i < string.length; i += 2) {
        arrayBuffer[i / 2] = parseInt(string.slice(i, i + 2), 16);
    }
    return arrayBuffer;
}
