topfew-rs's Issues

Output should display fields in the order given to -f

While topfew-rs deals with being given fields in any order unlike topfew (timbray/topfew#8) it still displays them in numerical order instead of the order given.

 $  /Users/bob/.cargo/bin/tf -f 9,7 test/data/small

I would expect it to do the same as the equivalent in awk

 $  awk '{print $9 " " $7}' test/data/small | sort | uniq -c | sort -rn | head
