Experimental: microbundled react-cytoscapejs

[akx]

About

As requested by @alexcjohnson in plotly/react-cytoscapejs#99 (comment) , this pulls in the plotly/react-cytoscapejs#99 version of react-cytoscapejs and adds cytoscape as a direct dependency (as it is a peer dependency of react-cytoscapejs going forward).

I ran npm run build:all and tried some of the demos/ – everything seems to work just fine.

• 👉 This PR should not be merged as-is, though, since the package.json specifier for react-cytoscapejs is not a published version. (That's why this is left as a draft.)

Description of changes

Please see above.
