> Add "Hoist", a utility to replace literals in a SQL string with placeholders.
> By default it uses Calcite's parser, but you can configure to use different
> quoting, casing, and also to use a different parser such as Babel for other
> dialects of SQL.
> It generates a data structure, {{Hoisted}}, that contains a map of where the
> literals occur within the SQL string. The Hoisted.substitute method generates
> an alternative SQL string, replacing the literals with a custom string.
> It does not call {{SqlNode.unparse}}, and therefore does not lose any of the
> original formatting.
> For more examples, see tests added to {{SqlParserTest}} and
> {{BabelParserTest}}.
