Issue adding the plugin to phaser3-typescript-project-template

Hello,

Thank you for sharing! I try to use your plugin with https://github.com/photonstorm/phaser3-typescript-project-template but I've some issues. I've added in `rollup.config.dev.mjs`:
```
commonjs({
include: [
'node_modules/eventemitter3/**',
'node_modules/phaser/**',
'node_modules/phaser3-swipe-plugin/**'
],
```

In the game.ts the lib is linked via `import { SwipePlugin } from 'phaser3-swipe-plugin';` but I got an `Uncaught ReferenceError: Phaser is not defined`. Any ideas?

Copy/paste your plugin code directly inside the game.ts works fine.

Start with rollup.config.dev.mjs and game.ts in the phaser3-typescript-project-template, reviewing the listed CommonJS includes and the import of phaser3-swipe-plugin. Reproduce the Uncaught ReferenceError: Phaser is not defined; done means the plugin can be imported and used without that runtime error, while the plugin code remains external to game.ts.
