Create our own integrated fork of Angular's Domino fork

[pavelhoral]

I am creating this issue to track activities related to fully adopting this Domino fork into Mixmark / Turndown.

What needs to be done:

• check licensing
• create forked repository under
• describe motivation behind this fork (why are we forking)
• update README - add disclamer similar to what Angular's team made
• update package.json - package will be deployed under @mixmark-io organization
• release and publish to NPM
• use in Turndown as a reference parser

Motivation behind the fork:

• Domino seems to be the best JS based HTML->DOM parser (Add happy-dom and benchmark turndown#457). However the last release was 4 years ago and there is no bugfixing being done in the repository.
• There are issues we would love to see fixed (e.g. error while running with webpack bundle in nodejs turndown#439). As our usage in Turndown requires only a very narrow subset of features Domino offers, we can fork the repo and build our own package that will serve as the default reference parser (related to Separate Turndown Core turndown#290).
• We are using Angular's fork as it provides a few fixes we want to have as well. Other than that our fork will be independent (we might pull changes from Angular when relevant in the future).

There are some Angular-specific changes in the Angular's fork (duh :P), but they seem harmless to our use case, for example:

domino/lib/NodeUtils.js

Lines 15 to 20 in 9e7881d

	// Export util functions so that we can run extra test for them.
	// Note: we prefix function names with `ɵ`, similar to what we do
	// with internal functions in Angular packages.
	ɵescapeMatchingClosingTag: escapeMatchingClosingTag,
	ɵescapeClosingCommentTag: escapeClosingCommentTag,
	ɵescapeProcessingInstructionContent: escapeProcessingInstructionContent

I don't want to invest effort in removing those or to create our own fork from the original Domino repo. I think we are better off having commits from Angular including their changes that are not relevant for us.

Turndown now uses this fork (mixmark-io/turndown#461). I consider this issue as resolved.
