Current version does not build

[brucealthompson]

I think there is a versioning issue between your github repository and the information that has been pushed to https://pkg.go.dev/github.com/biter777/processex.

Here are the issues:

1. The documented api is different between this github repository and https://pkg.go.dev/github.com/biter777/processex
2. I get the following error when I try to build the latest version:

github.com/biter777/processex
