FYI the comparison and sort kernels do not make use of this DynComparator, and I actually hope to at some point deprecate it in favor of the row format.

That may be but we were running into the unhandled case in this match firing when testing apache/datafusion#3911

Even better would be some tests with more than one value in the list, and some tests of more than just Ordering::Less, but don't feel strongly 😅

Closes #2904
Rationale for this change
Implementing sorting / grouping in datafusion on columns of type FixedSizeBinary requires that ord be implemented for FixedSizeBinary types.
