Enhancement request: add command-line functionality

[WrayOfSunshine]

Using Windows, I haven't found an effective tool to batch create torrents via CLI that allows for "auto" piece size. However, this tool (being focused on torrent creation) seems like it would be well suited to doing so. Please consider adding this functionality.

It is very necessary for the expansion of the functional with command line. Please take the time for such a function. We all will be grateful to you!
