Ouch is not giving a correct error message when trying to compress a folder with multiple single formats:
$ ouch compress linux.pkg linux.xz.gz.zst
Current Behavior
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', src/commands/mod.rs:102:49
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Expected Behavior
Something like this, when we just pass ".xz".
$ ouch compress linux-5.17.5.arch1-1-x86_64.pkg linux.xz
[ERROR] Cannot compress to 'linux.xz'.
- You are trying to compress multiple files.

- The only supported formats that archive files into an archive are .tar and .zip.
hint: Try inserting '.tar' or '.zip' before 'xz'.
