[FR]: Choice of valuta

[perfrank]

Describe the feature you wish to make a request for

I would like to chose the valuta in the config.

Describe alternatives you've considered

Could be a "Tick off" if default (Home assistant) or valuta in chosen country when creating an entry is presented.

Additional context

My HA server is localized "DK", which is fine in DK. But I also use Swedish data, and maintain local prices, fees and tarifs, which is in Skr. Having all prices in the same valuta will simplify calculations.
