kmerdb profile sort order returns improperly sorted col2, col3

[MatthewRalston]

The sort order is correct for col4 (i.e. descending counts) and col1 (fixed row number).

• Col 2 should be the index number of the sort (so... it should be the original unsorted k-mer id, since sort order is descending by count, not by id.) Indeed it seems

• col 3 should be just the k-mer id. (e.g. row 0 below: it should read [0, 65523, 65523, 1977, ...]

• Upon inspection, row 3 sort order is mangled.

Suggestion: remove col 3 so new column order is

• row number (fixed, ascending, 0 - 4^k)
• k-mer id
• count
• frequency
