* Array aggregator part 1 * Improve median testing * More testing * More testing * Update other dist tests * Add to the benchmark * Move errors into aggregator package, use from ddsketch; update Max/Min/Quantile to return errors for array/ddsketch/maxsumcount * Lint * Test non-absolute ddsketch * Lint * Comment * Add note
