Add testing for github workflows

Add some testing mechanism for github workflows and test (and debug) npm-publish workflow. Perhaps this tool helps?

I figured out how to test the npm-publish GitHub workflow.

In short, I

1. created my GitHub fork of the current repo,
2. made test-specific changes in this commit,
3. set the version to 0.1.17 in this commit with message Release 0.1.17, and
4. pushed both commits to master in my GitHub fork.

Then pascalgn/[email protected] did everything it was supposed to (while logging about it). Now the published version 0.1.17 is available here.

So, I am now confident in the correctness of the GitHub workflow. Here are the steps needed to use this GitHub workflow "for real".

One time

1. Complete PR Adds npm install steps to publish workflow #23.
2. Create a new GitHub secret with the name NPM_AUTH_TOKEN and with a value of a personal authentication token for your account on npmjs.com.

Every time

1. Change the value of the version key in package.json to x.y.z with desired values of x, y, and z.
2. Commit that change to master with message Release x.y.z using the same values of x, y, and z.
3. Push that commit to the current repository (if that commit was created in a fork of this repository).

I suppose one more thing you could do is download this version 0.1.17 that I published and manually inspect it to see if it as you expect it to be.
