Encountered problems while using.

I had some problems, when I tried the software. Btw I really like the idea of it, so please see this as construtive criticism.

First problem is, in "col2mid" "col2sort" is executed just by it's name, leading to an error, if it is not in your PATH.
Second: You need "bc" as requirement. It would be nice to add that in the readme.

Also, the outcome is very nice 👍

Thanks for your report, I'll see what I can do about it!
