Allow setting of `extract_to` when using `AndFeathers.from_path`

This change allows you to create an archive from a path, and specify the
extract_to field. For my purposes, it allows me to create a archive that
extracts all the contents into the current directory, instead of a directory of
the same name given.

Apologies or lack of test(s), or even running tests, time crunch. If you don't add one yourself, I can
add later. I also lack ruby 2.0.0 atm
