Autolinks with email addresses parse incorrectly

The following markdown:

```markdown

```

Renders incorrectly as:

```html

<foo@bar.baz>

The [CommonMark spec](https://spec.commonmark.org/0.29/#example-593) doesn't treat email addresses in autolinks specially. But this library has a special `EMAIL_AUTOLINK` token type that isn't parsed or rendered correctly:

```
Markdown:PARAGRAPH
Markdown:< '<'
Markdown:EMAIL_AUTOLINK 'foo@bar.baz'
Markdown:> '>'
```

I would suggest removing that token type.
