Add option --sort/--order

[don-rumata]

Hi. Can you add an option to sort columns in a table?

Now:

curl --silent http://<my-repo-in-intranet>/apt/debian/dists/stable/main/binary-amd64/Packages | /usr/local/bin/jc --pkg-index-deb -p | /usr/local/bin/jp "sort_by([], &package)[].{package: package, version: version, homepage: homepage}"  | /usr/local/bin/jtbl --markdown

| homepage                                       | package      | version    |
|------------------------------------------------|--------------|------------|

How i want:

jtbl --markdown --order=package,version,homepage

| package       | version       | homepage                                       |
