messydates: A Flexible Class for Messy Dates

Contains a set of tools for constructing and coercing into and from the messydt class. This date class implements ISO 8601-2:2019(E) and allows regular dates to be annotated to express unspecified date components, approximate or uncertain date components, date ranges, and sets of dates. This is useful for describing and analysing temporal information, whether historical or recent, where date precision may vary.
