Does the current environment have `import()` support?

At the time of this writing, node v12.17+, v13.2+ and v14.0+ has support for dynamic [`import()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import#dynamic_imports); the syntax is supported in node v10+.

The former can be checked in the package‘s main export, which is an `async function` that returns a boolean indicating if the current environment fully supports dynamic import. Note that in node v12.17 - v12.19 and v13.4 - v13.13, an ExperimentalWarning will be logged.

The latter can be checked with `'has-dynamic-import/syntax'`, which is a function that returns a boolean indicating if the current environment supports parsing the syntax of dynamic import.

## Tests

Simply clone the repo, `npm install`, and run `npm test`
