This PR fixes #1005

Work In Progress

Summary

This PR provides a simple way to add a static directory for the Robyn app and each SubRouter. It calls serve_directory but with fewer arguments and simple defaults. The goal will be to make it a one line addition eg

change from (in the initial example at https://robyn.tech/documentation/example_app/modeling_routes )

app = Robyn(__file__)

@app.post("/crimes")

to

app = Robyn(__file__)
app.add_static_files_directory() #using a sane default directory path and "static" as the route both customisable via arguments

@app.post("/crimes")

For the subrouter the same ( https://robyn.tech/documentation/example_app/subrouters_and_views )
'''
frontend = SubRouter(name, prefix="/frontend")
frontend.add_static_files_directory() #using a sane default directory path and "static" as the route both customisable via arguments

@frontend.get("/")
'''

what I want to support are these routes /static/crimes.css and '/frontend/static/fronts.css' (where frontend is the object name not the route prefix)

Then we can add support to templating allowing us simple access to static files in templates which won't change when the route prefix for frontend changes

get_static_url("crimes.css") 
get_static_url("frontend/fronts.css")
