Add support for Durgod Hades ISO version

[ebastler]

This PR adds support for Durgod Hades ISO, v2 (irrelevant as QMK PR has only just taken place) and v3.

Description

I renamed the ANSI Hades configs from hades.json to hades_ansi.json, and added hades_iso.json files.

QMK PR has been merged onto develop branch, not master, so not 100% sure if this will be accepted just yet? It will end up on master next dev merge.
