Support for custom elements (#45)

* Support for custom elements

Now you can use custom elements like so in Astro components:

```html
<script type="module" src="./datepicker.js">
<date-picker></date-picker>
```

These will be resolve relative to the current astro component. In the build these modules are run through the same bundle/minify process as components.

* Remove component from public

* Formatting

* Disable empty fn rule
