Description: A single-call data quality assessment scoring a data set
        on the five inherent characteristics of the ISO/IEC 25012 data
        quality model (accuracy, completeness, consistency, credibility
        and currentness) through the fifteen quality properties beneath
        them, ISO/IEC (2008) <https://www.iso.org/standard/35736.html>.
        Each property is measured as a ratio of counted data items, the
        form ISO/IEC 25024 measurement functions take, ISO/IEC (2015)
        <https://www.iso.org/standard/35749.html>. Six properties are
        computable from a table alone; the rest compare the data
        against expectations declared through a specification object,
        and are reported as not applicable rather than approximated
        when none is supplied. Also reports missing-data patterns,
        duplicates, redundant columns, outliers, multicollinearity and
        distributional deviations, and returns a structured object with
        plots rather than console text alone. The statistics implement
        the methodology of the author's master's dissertation, Demirhan
        (2024) "Assessing Data Quality Management Issues in
        Open-Sourced Data Sets with Statistical Methodology"
