QueryImpl.getMetaData() not implemented

Description

When attempting to use a Java library com.opencsv.CSVWriter 3.7's writeAll(ResultSet rs, boolean includeColumnNames) method I get the error

The library attempts to use the getMetaData() method but it was never implemented. This seems to be a part of the java.sql.ResultSet interface.

My guess is in the fillResult() method the QueryResult has a ResultSetMetaData returned by result.getMetaData(). It might be as easy as storing that into a class variable and returning it from the getMetaData() method.

I've checked this ticket and Now query.getMetaData() method is supported in lucee version 6.0.0.387-SNAPSHOT.

We need this as well and rather urgently. Please merge this in.

What is the feared performance impact? The RecordSetMetaData is already being used in the fillResult method, this does nothing more than persist it and it seems like only a slight amount of duplication of data. An alternative is to implement the RecordSetMetaData similar to ACF with QueryTableMetaData, where it seems to implement all the methods and more that it’s Query implementation requires, but that mostly seems like overkill to prevent needing to have the list of column names twice in memory.
