Vitocal200S support / XML file configurable

[RoP09]

Hello,

I have a Vitocal 200S which uses a different command set (see https://github.com/openv/openv/wiki/Adressen#adressen-um-werte-abzufragen-oder-zu-setzen), which I already used successfully for years in FHEM / VCONTROL.

Would it be possible to make the vito.xml editable so we can add custom commands to allow other devices?

Thanks!
