Adding device solar data endpoint

[psdupvi]

Issue #190

Adding endpoint for device solar data.

I limited the return values to just the specific solar data deviceSolarInput because it's already a lot of data, and I suspect we already return all the other data from the device settings endpoint

If the device has no solar data, it returns the following value (I tested with my non solar 945):

{'solarDailyDataDTOs': []}

With solar data, it returns something like the following

    {
      "solarDailyDataDTOs": 
          [ # List with one entry per day
              {
