String Series sortValues is Backwards

[sernst]

Describe the bug

When sorting a column of strings, ascending and descending behaviors are reversed.

To Reproduce

>> s = new dfd.Series(["2015-01-01", "2023-01-01", "2017-01-01", "2010-01-01"])

// 1. Sort values by default order, which from documentation says is ascending...
>> s.sortValues().values
//    Array(4) [ "2023-01-01", "2017-01-01", "2015-01-01", "2010-01-01" ]

// 2. Set explicit ascending: true...
>> s.sortValues({ ascending: true }).values
//    Array(4) [ "2023-01-01", "2017-01-01", "2015-01-01", "2010-01-01" ]

// 3. Set explicit ascending: false...
>> s.sortValues({ ascending: false }).values
//    Array(4) [ "2010-01-01", "2015-01-01", "2017-01-01", "2023-01-01" ]

Expected behavior I would expect string series ascending sort order to be ascending, and specifically match Array.sort ascending behavior strings.
