isoreader2 0.6.0

• Initial CRAN release.

• Reads stable isotope data files from many vendor formats: Isodat (.dxf, .cf, .did, .caf, .scn), IonOS (.iarc), LyticOS (.larc), Callisto (.bch), and Qtegra (.imexp), via the external isoextract helper (ir_read_isofiles(), ir_extract_isofiles()).

• Provides a consistent object model (ir_isofiles, ir_aggregated_data) with tools to aggregate (ir_aggregate_isofiles()), convert signal units (ir_convert_intensity()), calculate ratios (ir_calculate_ratios()), filter and extend metadata, and access the extracted data (ir_get_*()).

• Visualizes continuous flow, dual inlet, and scan data (ir_plot_continuous_flow(), ir_plot_dual_inlet(), ir_plot_scans()), and builds the underlying plotting tibbles directly (ir_generate_*_tibble()).

• Saves/loads data and exports to Excel (ir_save_isofiles(), ir_load_isofiles(), ir_export_to_excel()).
