Description: Data processing and generating stratigraphic sections for
        volcanic deposits and tephrastratigraphy. Package was developed
        for studies on Alaska volcanoes ("av") where stratigraphic
        ("strat") figures are needed for interpreting eruptive
        histories, but the methods are applicable to any sediment
        stratigraphy project. Plotting styles inspired by "SedLog"
        (Zervas et al. 2009) <doi:10.1016/j.cageo.2009.02.009> but with
        more customizable outputs and flexible data input based on best
        practice recommendations for the tephra community (Wallace et
        al. 2022) <doi:10.1038/s41597-022-01515-y>.
