Curate actual weather data for validation

[jessicaguo]

Debasmita + Arun asked for actual weather data from 2021, to validate the accuracy of the weather forecasts used. Daymet data is available for the first 6 months of 2021, but in a provisional form not accessible to 'daymetr' functionality.

• [x] obtain and upload the daymet .cdf files to the data/ folder on Welsch
• [x] extract radiation, max_temp, min_temp, and precipitation for the 8 NEON sites

Alternatively, use the weather data locally collected at NEON sites to obtain the same variables. Discuss with Kristina about approaches.

There were difficulties in working with the 2021 Daymet data. The .nc files that are provided use a lambert conformal conic projection, so the netcdf has two dimensions for both x and y. This requires being careful about how to get data for desired lat lon coordinates.

The daymetr package is designed to work with the single location data provided by Daymet, so can't be adapted to this need.

We're going to use the NEON site sensor data instead. So far we have min and max daily temp for the sites from here and daily precip from here. See PR for code. Still need to add radiation, though NEON provides data from multiple sensors.

See PR for efi_forecast_weather_validation.csv that has daily values for the eight forecasting sites for precip, min and max temp, radiation, and VPD.
