For all TTS CE users in need of an unofficially official EUI

[https://descartes.co.uk/CreateEUIKey.html](https://descartes.co.uk/CreateEUIKey.html)

Derived from [DevEUI for non-hardware assigned values - #23 by terrillmoore](https://www.thethingsnetwork.org/forum/t/deveui-for-non-hardware-assigned-values/2093/23)

This fills the temporary hole left by the v2 console not being available to generate DevEUI’s when registering a new device that doesn’t come with an official EUI.

To avoid potential clashes with others, for missing App/JoinEUI’s, please use all zeros as recommended on the console.

For AppEUIs please use all zeros. There is no need to use a random value there.
