> Implement support for CASE in vectorized mode. The approach is to use the vectorized
UDF adaptor internally. A higher-performance version that used VectorExpression subclasses
was considered but not done due to complexity. Such a version potentially could be done in
the future if it's important enough.
> This is high priority because CASE is a fairly popular expression.
