Fixes #6

The only thing required to fix #6 is adding |raw in the twig template. That's it. Four characters. I did a bunch of other stuff while figuring this out. If there's too much stuff and you don't feel like pulling this I can make a simpler PR with less changes.

Changelog:

• Ran a formatter on the changed files
• Declared all dependencies (and added tested versions)
• Refactored id extraction and insertion
• Now handles invalid id from shortcode eg. grav-id="id with spaces". It generates a new id if the one in parameters is invalid.
• Add support for id shortcode parameter while keeping backwards compatibility with grav-id
• Prioritize the id passed through parameters. If there's an id in the shortcode content AND in the parameters, the id is replaced with the one in the parameters.
• Used twig |escape('js') to escape the options for DataTable. This in combination with JSON parsing the options allows passing more complicated options than just true / false
• And of course used |raw in the template to output the table as HTML
