Interface is counterintuitive

[OrderFromChaos]

Is your feature request related to a problem? Please describe.
Methods related to client's request (get_json, get_text, get_data) are inexplicably methods of AppResponse instead of AppRequest. The AppRequest presumably refers to the data sent from the client and is used as such for other client message methods like get_headers, get_cookies, get_url, etc.

Describe the solution you'd like
All methods related to client's request should be part of AppRequest.

Describe alternatives you've considered

Additional context
Minimal example (version 0.0.27):

from socketify import App
async def root(res, req):
    print(type(res))
    print(await res.get_json())
    res.end("Hello World socketify from Python!")
app.post('/', root)
app.listen(17999, lambda config: print("Listening on port http://localhost:%d now\n" % config.port))
app.run()

Then:
curl -d '{"key1":"value1", "key2":"value2"}' -H "Content-Type: application/json" -X POST http://localhost:17999/

Which gives:

Listening on port http://localhost:17999 now

<class 'socketify.socketify.AppResponse'>
{'key1': 'value1', 'key2': 'value2'}

this is because of how uWS was created, I'm redoing the interface. Will keep this open until is finished.
