`xxxFor {}` functions in statistics unreasonably strict

[Jolanrensen]

df.maxFor { age and name } is not allowed, even though the result would be a DataRow containing the maximum value for each column independently.

df.maxFor { (age and name).asComparable() } works fine, so it's just the type limitation.

It's probably fine to change the type to C : Comparable<*>? for these particular functions, as C is never used in a reified way.

This also applies to medianFor, and percentileFor

✅ The execution was successful

The type constraints for the statistics functions maxFor, medianFor, and percentileFor in a dataframe were relaxed from C : Comparable<C> to C : Comparable<*>?, allowing for more flexible type usage. Changes were successfully implemented across relevant function declarations and also included necessary test validations. There were no errors reported during the implementation process.
