Parameterize render sanitization + Deep general sanitization

[araluce]

There are two changes in this request:

1. The sanitize helper now performs a more thorough sanitization and is ready to accept different types of objects. (We moved the enhanced sanitise from templates to the generic helper).
2. Sanitization options can now be added to the insertHTML and render helpers.

@araluce maybe we should move here too this code block still in templates?

// Handle null and undefined values in output by replacing them with empty string
if (typeof output === 'string') {
  return output.replace(/\bnull\b/g, '').replace(/\bundefined\b/g, '')
}

The original idea of this method is to use with "sanitize false", as we only need to sanitize data, the template is controlled by us. Otherwise I'm not sure if this method makes sense 🤔?

In general, I'd like to keep Ralix rendering as safe as possible by default, but at the same time we need to provide good ergonomics to work with the framework (passing "sanitize false" seems like an exception).
