Web worker chapter

[sverhoeven]

As C++ developer I would like to know how to run the root finding algorithm in the background in Javascript.

Acceptance criteria:

• Someone (aka reviewer) is able to understand and run example
• Testing of chapter is automated

Tasks:

• Adapt code block with worker consumer s to root finding algorithm
• Code block with worker provider
• Code block & command to run example from NodeJS
• Include running example in Github Actions
• Explain how to run from browser, will need a index.html file

With cypress we can test in web browser so do not need to test with NodeJS. See #21
