Solcast integration with `delta_forecast` > 1 fails

Describe the bug
Using solcast forecast model together with delta_forecast set to value > 1 fails with:

ERROR - Not enough data retrived from SolCast service, try increasing the time step or use MPC

EMHASS installation type

Docker Standalone

Additional context
Without testing or adjust, IMO problem comes from the fixed time frame when calling the API:

emhass/src/emhass/forecast.py

Line 238 in d06b829

    
           url = "https://api.solcast.com.au/rooftop_sites/"+self.retrieve_hass_conf['solcast_rooftop_id']+"/forecasts?hours=24"

Value of hours should be a factor of delta_forecast to be compatible with the expected number of results. As far as I could see requests are not limited to 24 hours only. Otherwise startup of app should already fail in case of invalid configuration parmeters.

Hi. Yes you are right, this is hard coded to retrieve just 24h of data.
Yes we could make it a function of the passed delta_forecast.
But then we need to know what is the maximum possible period to retrieve data from SolCast.
We need to check that on the SolCast API.

Hi, just solved this for out 3 methods available inside EMHASS.
This will be available in the next release.

Here is the result for delta_forecast=2:

Solved in the just released new version.
Closing this for now but reopen if eneded.
