Cache response from

[faanskit]

Hey,

I have working code on-top of PR #5 that caches the response to reduce number of requests to Wyze, leading to long response times when having many cameras and sensors.

The source comes from this page and extends the lru_cache decorator:

def timed_lru_cache(seconds: int, maxsize: int = 1024):
    def wrapper_cache(func):
        func = lru_cache(maxsize=maxsize)(func)
        func.lifetime = timedelta(seconds=seconds)
        func.expiration = datetime.utcnow() + func.lifetime

        @wraps(func)
        def wrapped_func(*args, **kwargs):
            if datetime.utcnow() >= func.expiration:
                func.cache_clear()
                func.expiration = datetime.utcnow() + func.lifetime
            
            return func(*args, **kwargs)

        return wrapped_func

    return wrapper_cache

For this to be effective, the the request will not filter on mac on the request. Instead, a larger list will be fetched and cached.

get_latest_event() -> get_event_list() -> NEW and CACHED get_complete_event_list()
get_events() -> get_event_list() -> NEW and CACHED get_complete_event_list()

Since it extends PR #5, I hesitate to push updates before merged. This new code addresses parts of the issue 168 in ha-wyzeapi.

The more sensors added per camera, the more cameras used - the worse it gets.
With three cameras and all four sensors enabled (Motion, Sound, CO2 and Smoke) - frequenzy of this error occurs:
2021-05-18 20:04:12 WARNING (MainThread) [homeassistant.components.binary_sensor] Setup of binary_sensor platform wyzeapi is taking over 10 seconds.

Caching highly required. I'll PR when you are ready. Either as part of #5, or after merge of #5

Now added to PR #5
