    if sums.len() != bytes.len() {
        panic!("Help how do I error handle this?")
    }

Looks like I forgot to implement proper error handling in this location, sorry.
I'll have to fix this when I have time.

Anyway, this should pop up if the number of checksums provided doesn't match the number of files provided.
Were there maybe other *.bin files in the same folder?

Oh, right. I had copied one of the files to try something.
