Command line options not working on Win

[marcodeppe]

Hi! Thanks so much for creating this useful toolkit :)

I noticed that the command line options didn't work on windows.
It made no difference if I appended the --help param. If I added the input param it still prompted me for the directory the same way as if I didn't specify it. I ran them like this:

# Run with specific options
cargo run --release -- --help

# Process specific folder
cargo run --release -- --input "/path/to/folder"

# Custom output directory
cargo run --release -- --output "/path/to/output"
