Add resource loading in jinja templates

[sansyrox]

For the jinja implementation would it be possible to add something to load the resources like Flask:

{{ url_for('static', filename='images/planets.jpeg') }}
or Starlette :

{{ url_for('static', path='images/planets.jpeg') }}
or for a route:

{{ url_for('/') }}
Because currently using url_for makes the template crash and returns a 500 error ...

Out put this point the integration of jinja works well good job ;)

We will have to include the work done in this PR - https://github.com/sparckles/Robyn/pull/738/files

And then build upon it !
