fix: seek row for sorted columns

[wusteven815]

• Change algorithm for sorted columns
  • Use SortedColumnsAttribute.getOrderForColumn instead of guessSorted to guarantee
  • Add a binary search algorithm to find first/last occurrence in a sorted list
  • Check next/prev row first, then loop around to end/start and get last/first occurrence
    • e.g. for [1, 2, 2, 3] and on the last 2, the algorithm would check the next value (3) first, then search for first occurrence of 1, 2, 2
• Change algorithm for unsorted columns to return -1 when not found, instead of the closest value
• Replace ConcurrentMethod with snapshots

If we're confident we know what's wrong here, can we add a unit test or two to verify behavior?

I'm spending a little time this morning going over the test cases, might propose a patch to add more meat to the tests to ensure we don't need to revisit again.

Also, I will probably propose a change to chunk the non-sorted cases to make them more efficient (so again the tests will help there).
