afsetools 0.3.0

BNF functions module (R/bnf_functions.R): 5 exported functions for biological nitrogen fixation — calc_crop_bnf(), calc_weed_bnf(), calc_nonsymbiotic_bnf(), calc_bnf(), and summarize_bnf() — with literature-based environmental modifiers for temperature, water stress, soil organic matter, pH, and clay content.
IPCC biomass coefficients: 6 new sheets in Biomass_coefs.xlsx with crop residue, root, and mapping coefficients verified against IPCC 2006 Vol.4 Ch.11 Table 11.2.
Data-driven NPP model: NPP model coefficients extracted to Excel (NPP_model_coefs sheet). calculate_potential_npp() now reads coefficients from the data table instead of hardcoded literals.
Simple mode for crop NPP functions: calculate_crop_npp(), calculate_crop_residues(), calculate_crop_roots(), and calculate_npp_dm_c_n() gain a mode parameter ("full" / "simple") that auto-detects available columns and adjusts calculations accordingly.
Crop-group-specific residue/root helper data: new lookup tables for residue shares, weed NPP scaling, fallow cover, and root-shoot N response.
Feed distribution: redistribute_feed() function for multi-level feed allocation with diagnostics, plus max_intake_share loaded from Livestock_coefs.xlsx.

Fixed crop-specific irrigation residue factor and reduced rice HI_gap_factor.
Fixed N-input root-shoot adjustment: calculate_crop_roots() now uses the N_input_RS_adj data table via findInterval() instead of ignoring it.
Added DescTools and zoo to package dependencies (previously undeclared).
Fixed stats::quantile() call in calculate_footprints() draught share calculation (was missing namespace prefix).
Replaced non-ASCII box-drawing characters in redistribute_feed() diagnostics with ASCII equivalents for portable package compliance.
Fixed %!in% operator documentation to avoid invalid Rd \name field.
Moved unused data.table and readxl from Imports to Suggests.
Added comprehensive globalVariables() declarations for all NSE column names across the package (eliminates R CMD check NOTEs).

Expanded DATA_REFERENCE.md to 80+ objects with IPCC and NPP sections.
Complete roxygen2 rewrite for calculate_potential_npp() and NPP model coefficient documentation.
Added Names_BNF, Pure_legs, NPP_model_coefs, and max_intake_share to pkgdown reference index.
