Support Cython

I get this error :
AttributeError: 'method_descriptor' object has no attribute 'module'

File "C:\Users\fff.conda\envs\biconome\lib\asyncio\base_events.py", line 579, in run_until_complete

The version that I used is ' pip install aiocache==0.10.0' and ' aiocache-0.11.1'

`cdef class BaseMarket:

_CACHE_ = Cache()
cdef str symbol
cdef dict __dict__

@classmethod
async def http_request(cls, url, data=None,accept="json",timeout=1) -> any:
    _timeout = aiohttp.ClientTimeout(total=timeout)
    async with aiohttp.ClientSession(timeout=_timeout) as client:
        try:
            if data == None:
                _temp_cache = await BaseMarket._CACHE_.get(key=f'res_data_{url}')
                if _temp_cache:
                    res_data =  _temp_cache
                else:

                        ...
        except TimeoutError as te:
            print(f"Timeourt Error from {url} accurred <{str(te)}>")

cdef class SOMECLASSMarket(BaseMarket):

def __init__(self,
             symbol: Optional[str] = None,
            ):
    super().__init__()
    self.symbol = symbol

@classmethod
def split_symbol(cls, symbol:str) -> Tuple[str,str]:
    pass

@classmethod
def http_request(cls) -> any:
    return SOMECLASSMarket.http_request(cls)
    pass`

the code is like that

the Cython version is 'cython==0.29.5'

Hey sorry for the delay, I never tested compatibility with cython. I guess the error is because of how the decorator introspects the arguments of the function and so. I you want to have a look to support Cython I'm happy to review :)
