By default, skip the following when creating a torrent:
- Junk files, like `Thumbs.db`
- Files and directories that begin with a `.`
- Files and directories that have the OS or Windows hidden attribute set
- Symlinks
These can be overridden with, respectively:
- `--include-junk`
- `--include-hidden`
- `--include-hidden`
- `--follow-symlinks`
type: changed
When no piece length is provided to imdl torrent create, a piece
length is selected based on the size of the input. The hueristic is
lifted directly from libtorrent.
Also adds a imdl torrent piece-length command, which prints a table
of the piece lengths chosen at different content sizes, which is useful
for understanding and debugging the piece length selection algorithm.
