WIP package to compute and get meteorological or climatic data related to plant growth.

• Use an efficient structure for the meteo data (TimeStepTable{Atmosphere})
• Add a generic interface for the weather forecast and history APIs
• Add one meteo API (open-meteo)
• Add a function for integrating sub-daily data into daily data, and check that sum(durations) == 24 hours
• Add function to write meteo data (avoiding to write computed variables such as ρ or λ)
• Add function for sampling historical data with e.g. temperature quartiles.
• Add more APIs
• Add functions for computing sub-daily data from daily data
• TimeStepTable: Ensure that we don't copy the data when transforming to e.g. DataFrame. Related to #19.
• TimeStepTable: Use views when indexing for better performance.
• write_weather: don't transform into DataFrame for selecting columns? If so, implement a select of use the one from TableOperations.jl. Related to #19.
