Return native voltage value

[mib1185]

This removes the division by 1000 on voltage value, since all other powermeter values are also returned "native"

• this will also fix fritzbox: Entities _electric_current and _voltage wrong multiplier/divisor 0,230V instead 230V home-assistant/core#73224

Wouldn't it be better to divide power too so we return proper values and can remove the divisor in Home Assistant? I think this is what users would expect from pyfritzhome.

TBH I would always prefer, that the native values are returned, so the user of this library can decide if he want's to calculate with mV and mW or V and W 🤔

[flabbamann]

I guess its personal preference if you prefer to have mV and mW or V and W 😃
@hthiery your thoughts on this? The way it is now I'd say it is definitely a bug 😉.

Sorry for the long delay . I will merge as is. Thank you.
