Initial CRAN submission.
New analysis functions:
load_india_boundaries(), spatial_mean(), compare(),
cross_correlation(), anomaly(), seasonal_cycle(), peak_month(),
seasonal_stat(), regrid() and dewpoint_from_relative_humidity().
New ggplot2 plot functions: plot_map(), plot_series(),
plot_dual_axis(), plot_ccf(), plot_scatter(), plot_bars() and
plot_heatmap().
era5ify_*() with frequency = "monthly" or "yearly" return totals for
accumulated variables such as precipitation (they returned the mean daily
value), and always have year (and month) columns.
era5ify_point() snaps its download box to the 0.25 degree grid, so the
nearest cell is a true ERA5 grid point.
era5ify_*() with frequency = "yearly" download the ERA5 monthly-means
product, as in the Python package. Before, they downloaded one value at
12:00 for each day.
Shared test cases in parity check that R and Python give the same
results.
