apsimeval 0.1.0

• First release.
• read_out() and read_out_dir() parse ‘APSIM’ Classic .out files, keeping units per column and treating ? as missing rather than zero.
• gof() reports the calibration and validation statistics used in crop-model papers, including the Willmott decomposition of RMSE and the standard deviation of the observations alongside RMSE.
• plot_series() draws multi-variable, multi-treatment timelines with an optional secondary axis and calibration/validation shading.
• sens_anova(), sens_oat() and sens_range() quantify the sensitivity of an output to treatment factors.
• build_figure() assembles panels into a manuscript figure; save_pub() writes it at journal column widths.
• run_app() starts a ‘shiny’ interface that refreshes incrementally as ‘APSIM’ rewrites its output.
