'handle_rate_limit' incorrect behaviour

Description:

When creating an instance of Client (found in twitter_ads.client) you can pass a dict with additional options, using the options parameter. One of this options is handle_rate_limit. When passed, the library is supposed to look for the rate limit headers returned by the API and sleep the execution when such a limit is encountered. However, it would appear that the wait time is insufficient, as the next request after the wait period fails with a rate limit error.

How to replicate:

client = Client(**config, options={'handle_rate_limit': True})
...
for chunk_ids in split_list(ids, 20):
    analytics_data: List[dict] = Campaign.all_stats(
        account,
        chunk_ids,
        [METRIC_GROUP.ENGAGEMENT, METRIC_GROUP.BILLING],
        granularity=GRANULARITY.TOTAL,
        start_time=export_range.start_date,
        end_time=export_range.end_date
    )

The above code is ran for an export range of one day. It is repeated for multiple accounts. This is the output when a rate limit is reached:

time=2022-07-26 17:22:50 name=twitter_ads.http level=WARNING message=Request reached Rate Limit: resume in 592 seconds

Expected behaviour:

The library should wait the appropriate amount of time before attempting to call the API again to completely avoid RateLimit errors.

Observed behavior:

At the current state, the handle_rate_limit option serves no purpose. Despite waiting a certain amount of time, the rate limit error is encountered anyway.
