Changes in version 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()).
