OATH Applet doesn't work

[tao-harald]

Canokeys info: Model: CanoKey ES (STM32) Firmware Version: v2.2-12-gd2813250-dirty-O (forked version: https://github.com/tao-harald/canokey-stm32/tree/nucleo ) System: Windows and Arch Linux

It seems that the problem is caused by src/Oath.js#L76 wich doesn't work as expected:

function isOldProtocol(firmwareVersion) {
  return firmwareVersion < "1.5";
}
