add annotations for resolve container

[chesnokpeter]

before:

import punq
import abc
cont = punq.Container()

class AbsConnector(abc.ABC):
@abc.abstractmethod
def connect(self):
raise NotImplementedError

class HelloConnector(AbsConnector):
def init(self):
print('init...')
def connect(self):
print('connect to hello ...')

cont.register(AbsConnector, HelloConnector, scope=punq.Scope.singleton)
conn = cont.resolve(AbsConnector)

conn.connect() # no hints

after:

conn.connect() # with hints for AbsConnector

Hey friend! I'm thinking I want to do this for a breaking version 1.0, since it will require deprecating the ability to use non-type keys, so I will come back to this in due course. Thanks for the starter!
