> When using filter MultiRowRangeFilter with ranges closed to each other that there are
no rows between ranges, then OutOfOrderScannerNextException is throwed.
> In filterRowKey method when range is switched to the next range, currentReturnCode is
set to SEEK_NEXT_USING_HINT (MultiRowRangeFilter: 118 in v1.1.0). But if new range is already
contain this row, then we should include this row, not to seek for another one.
> Replacing line 118 to this code seems to be working fine:
> {code}
> if (range.contains(buffer, offset, length)) {
>     currentReturnCode = ReturnCode.INCLUDE;
> } else {
>     currentReturnCode = ReturnCode.SEEK_NEXT_USING_HINT;
> }
> {code}
