Creates a new torrent using mktorrent with some sensible defaults:
--no-date
Finds a README file and uses that as the comment
Picks up a list of trackers from ~/.config/trackers.txt

Run as create-new-torrent --any --other-options /path/to/directory

Most common options you might want to overwrite are
--output
--name
