Review comment:
Before this change, I had a vector of 1000 items all on one line. After this
change, the output is 40 elements per line. Note that this code is used only
during debugging.

> Enforce column-level constraints when using a schema
> ----------------------------------------------------
>
> Key: DRILL-7143
> URL: https://issues.apache.org/jira/browse/DRILL-7143
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.16.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Major
> Fix For: 1.16.0
>
>
> The recently added schema framework enforces schema constraints at the table
> level. We now wish to add additional constraints at the column level.
> * If a column is marked as "strict", then the reader will use the exact type
> and mode from the column schema, or fail if it is not possible to do so.
> * If a column is marked as required, and provides a default value, then that
> value is used instead of 0 if a row is missing a value for that column.
> This PR may also contain other fixes the the base functional revealed through
> additional testing.
