Update spec tests and readme

This commit includes:

* Readme update to use `jasmine` instead of the abandoned `jasmine-node`
* validation_spec updated to use `tmp` to create a temporary file to
  validate against; the old logic looks like it was written for a
  synchronous runtime, and that's not how things work anymore.
* htmlbook_spec update is just to remove an unneeded `require`

 There are two suites of tests for this repository. The first is `spec/htmlbook_spec.js` and tests the package for expected output. Run this test with the following:
 
 ```bash
-$ jasmine-node spec/htmlbook_spec.js
+$ npx jasmine spec/htmlbook_spec.js
 ```
 
 The second test suite checks to be sure that the file being tested in `htmlbook_spec` are in fact being output to valid HTMLBook. It's no use writing tests that pass unless they pass on valid output. These tests are separated because the validation takes longer.
