TibberHome.update_info_and_price_info with parameter to change the resolution of Price_Info

[Godionplus]

The new Tibber API allows to request the Price_Info with the resolution QUARTER_HOURLY or HOURLY. For many reasons it is necessary to change the resolution. But the current implementation of pyTibber requests always only the QUARTER_HOURLY resolution.
This pull request includes the changes to add to the TibberHome.update_info_and_price_info function an 'resolution' parameter. In addition, the new const RESOLUTION_QUARTER_HOURLY has been added. Also the gql_query 'UPDATE_INFO_PRICE' has been changed to add the resolution as parameter.

I hope these changes comes to the master branch, in order to give everyone the possibility to change the resolution in the Price_Info request to the Tibber API.

Why do you need this? You can always aggregate the quarterly prices if needed?

Hi Daniel,
thanks for investigation my changes.
Sorry for the codecheck error. I forgot to add the import of RESOLUTION_QUARTER_HOURLY. I hope now everything is fine.

You ask about the sense of my changes.
You are right, it is possible to aggregate the quarter values.
But there are three reasons for my changes:

1. Wy should the user of pyTibber complicate his code? It makes no sense to implement aggregation of values, if you get these values simply by calling the Tibber API with the appropriate parameter. Annotation: There are still some cases in house automation to handle/calculate with hourly prices.
2. The call for 'PriceInfo' at the Tibber API (https://developer.tibber.com/docs/reference#priceinfo) got an additional parameter to change the temporal resolution. Therefore pyTibber should also offer the possibility to use this parameter.
3. To allow still to get hourly prices with pyTibber, makes it backwards compatible to the old behavior, since there where only hourly values available. (This is my current case, I have to use the new pyTibber with a existing code.)

Let me know what do you think.

beste regards,
Carsten
