Idempotent photo/video file organizer.

Given a `<src>` and `<dst>` directories:

1. finds photo-or-video files in `<src>`
2. fetches their [Exif]https://en.wikipedia.org/wiki/Exif data
3. computes their hash digests
4. moves-or-copies them into
   `<dst>/{<img-dir>,<vid-dir>}/<year>/<month>/<day>/<date>--<time>--<digest>[.<extension>]`
   where `<img-dir>` and `<vid-dir>` default to "img" and "vid", respectively,
   and are customizable via CLI.

Example:

```sh
$ phorg /mnt/usb-drive $dst move
$ cd $dst
$ tree .
