> Perhaps this should be part of replacing super columns with composites, but we essentially
need something analogous to sub-column validators for when composites are used in a way that's
similar to super columns (multiple fields for each "super column" in a row).  As an example
use case, suppose you have a wide row holding users where the comparator is (<user_id>,
<field>), and <field> might be either "name" or "age"; ideally, you can validate
"name" as UT8Type and "age" as IntegerType.
> Allowing wildcards to be used for components in the column name portion of the ColumnDef
might be a reasonable approach.
