Remove @ungap ponyfills

## Usage

Add `remove-ungap` to your babelrc plugins if the ponyfills are not needed by your

browser target.  This could be due to only targeting modern browsers or because

your project already polyfills the browser.

This plugin works with CJS and ES modules before bundling.  It can be run by

`rollup-plugin-babel` before import or require statements are altered.

### `exclude` option

You can add the `exclude` option to block removal/processing of specific @ungap modules.

```js

{

	plugins: [

		['remove-ungap', {

			exclude: [

				'@ungap/essential-map'

			]

		}]

	]

}

```

This config will cause any import of `@ungap/essential-map` to be preserved.

### `future` option

Some `@ungap` polyfills are needed by most current browsers or did not exist when the

current semver-major of this plugin was released.  These are only processed if explicitly

requested by the `future` option.  For example:

```js

{

	plugins: [

		['remove-ungap', {

			future: [

				'@ungap/from-entries'

			]

		}]

	]

}

```

Unknown modules are ignored.
