is_valid_column_values

This function checks that for any column schema, the max values
(e.g., max_string_length, max_date) are not less than the corresponding min values
(e.g., min_string_length, min_date). If any such inconsistency is found, an error
is raised with a descriptive message.

Validates data frames against a defined schema. Produces a report of the checks performed and any issues found, with index and entry value where appropriate. Backend checks are performed using pointblank Richard Iannone et al (2025) <doi:10.32614/CRAN.package.pointblank>.
