Description

General Updates

1. Updates the build system to use tsc rather than babel
2. Removes unused dependencies
3. Removes test runner dependencies (enzyme) in favor of @testing-library/react
4. Updates eslint ergonomics to ensure React best practices
5. Pulls EventEmitter from @formio/js
6. Updates documentation
7. Removes stale types
8. Removes stale tests
9. Adds jest and @testing-library/react so we can write and maintain a modern test suite

Updates to Components (<Form />, <FormBuilder />, <FormGrid />, <SubmissionGrid>)

1. Fully types the component and its props
2. Reorgs the code so as not to instantiate utility functions in the render function
3. Updates the src prop to resemble the createForm API (i.e. it takes either a form definition or a form url)
4. Renames some props to conform to idiomatic prop names (see below)
5. Consolidates effect functions
6. Updates the render element and instance state to use React reference values
7. Introduces useFormioContext and usePagination hooks
8. Introduces a styling API that decouples each component from Bootstrap

Breaking Changes / Backwards Compatibility

**** PLEASE READ **** This update introduces a number of breaking changes to the library, namely in the form of new hooks, new context consumer requirements for the <FormGrid />, <FormEdit />, and <SubmissionGrid /> components, and updated prop names. Additionally, the new styling API for <FormGrid />, <FormEdit />, and <SubmissionGrid /> are no longer coupled to Boostrap - anyone using those components will need to re-style them.

How has this PR been tested?

I've loaded this PR into a simple Next.js application to ensure everything works as expected. Also, now that we've moved away from karma, I expect to add more tests in the next major PR to this library. I did however add a small few tests.
