Start to modernize recompose (...)

[brody4hire]

updated:

• Switch to internal __createFactory function to resolve #806
• Update some code to avoid one of the warnings in React 16.14.0
• Update some dependencies (in devDependencies)
• Some other minor updates

Some TODO items:

• [ ] I would like to find a way to test the dist artifacts before updating the build-related dependencies.
• [ ] I would like to support multiple rxjs versions.
• [ ] Improve testing & support for multiple React versions
• [ ] Ideally test with Preact as well
• [ ] A number of dependencies are still outdated, some of which will likely need updates to the code base as well.
