HTML minification parser error

Describe the bug HTML minification breaks if there is a < in a <mj-raw> section.

To Reproduce Steps to reproduce the behavior:

1. Create a file with this MJML code:

<mjml>
  <mj-body>
    <mj-section>
      <mj-column>
        <mj-raw>
          {% if foo < 5 %}
          {% endif %}
        </mj-raw>
        <mj-text>Hello World</mj-text>
      </mj-column>
    </mj-section>
  </mj-body>
</mjml>

1. compile using the API:

const output = mjml2html(file.contents.toString(), {
  minify: true,
  filePath: file.path,
})

1. See error:

Error: Parse Error: < 5 %}

Expected behavior Expected minified HTML to succeed

MJML environment (please complete the following information):

• OS: MacOS 10.14.3
• MJML API Version 4.3.1

Maybe @timc13 solution is better then, let’s mention it to the doc instead 🤔

That could be done too but as minify is optional it’s a bit weird to have attribute for a potential option ?
