Add time resolved simulation results

[FlorianK13]

We can provide time series data of SolarIrradianceData, see https://open-pv.github.io/simshady/classes/index.ShadingScene.html#addsolarirradiance

We have hosted our skydomes in these formats:

• https://api.openpv.de/skymaps/irradiance_{lat}_{lon}_2018_01.json
• https://api.openpv.de/skymaps/irradiance_{lat}_{lon}_2018_yearly.json

Right now we use yearly, but we could also use the 01-12 jsons to get monthly resolved results.

Changes that would be needed:

• Simulation:
  • we save 12 results per simulatedTriangle in the simulationMesh
  • Update simshady to > 0.2.1 to have filtering by angle enabled
• Frontend:
  • we show 12 bars with monthly yield in the results page, which we obtain similarly to the yearly yield
