Can't reach a specific data-point via json selector, because of the dynamic selector (date/time)
## Who will benefit?
<!-- Will this fix a problem that only one user has, or will it benefit a lot of people !-->
I think a couple of people try to use the api to enter a specific data-point.
## Benefits and risks
<!--
What benefits does this bring?
- automate labour intensive tasks
- possibility to enter a specific data-point via json selector
What risks might this introduce?
!-->
## Proposed solution
<!-- How would you like to see this issue resolved? !-->
result should be provided as an array
## Examples
** "result": [
{ "2023-10-24": 2760 }
{ "2023-10-25": 8248 }
],**

For excample today it is only 2kWh on a 5.4kWp.

The included image is fetched from Home Assistant with both the forecast.solar integration, and a rest api sensor as well. Not sure how well the colors are seen, but here is an explanation:
Orange: today forecast using api, updated every 30 minutes.
Blue: forecast for tomorrow, else same as above
Red: the sensor for what is expected in 24 hours, fetched from the Home assistant API
Purple: the same as above, but in 12 hours
Yellow: actual output from the inverter
green: What the API gives at the beginning of each hour.
There might be a small error in the api-call, that the azimuth is -18 in the call, but should be -25, but when I run the api manually with -18 or -25, there is not much difference.
For yesterday, the peak power was 5510watts, while forecast.solar estimated 4610.
Here is the url I'm using (I've left out the api-key): http://api.forecast.solar/estimate/58.35/8.59/22/-25/7
Not sure what the history-call should output, I get almost the same as the estimate, that is today, and the next few days. I would expect maybe today, and the last few days.
The total estimate (from forecast.solar) for the days, fetched from the end of each day:
2022-04-13: 28651 Wh
2022-04-14: 28907 Wh
2022-04-15: 28979 Wh
2022-04-16: 34750 Wh
2022-04-17: 34357 Wh
2022-04-18: 29541 Wh
2022-04-19: 33783 Wh
The real production for the same dates
2022-04-13: 7.1 kWh (the weather was not as the forecast )
2022-04-14: 11.8 kWh (Same bad weather forecast)
2022-04-15: 44.2 kWh
2022-04-16: 43.3 kWh
2022-04-17: 43.2 kWh
2022-04-18: 43.9 kWh
2022-04-19: 42.0 kWh
When the wether is nice, I always get ~20% more than what forecast.solar says. Should I increase the kwp parameter of the call, and add max inverter output as well ?
