Proposed changes

This enhancement will make use of cddl and cddl2ts to generate a type safe interface for WebDriver Bidi.

It downloads the latest CDDL from the WebDriver Bidi specification (from their master branch) and can always generate an updated interface. This PR will also update the docs to reflect these interfaces:

For this change I wrote a little blog post to explain the reasoning for it. I further ideas how we can move this into the webdriverio package to make the bidi interfaces easier accessible without having to deal with low level protocol bits.
