[Bug-datamash] Please add a "range" operation to datamash

[Kingsley G. Morse Jr.]

O' great command line stat-fu ningas!

First of all, thank you very much for maintaining
datamash.

I love adding stats to the command line.

Humble suggestion:

Add a "range" option.

It would report the range of values in a column.

For example:

    $ echo -e "1\n2\n3" | datamash range 1
    2

Thanks,
Kingsley
