Aiohttp-client-cache

[See all issues & PRs for v0.6](https://github.com/requests-cache/aiohttp-client-cache/milestone/5?closed=1)

- Add a `bulk_delete()` method for all backends to improve performance of `delete_expired_responses()`
- Update session cookies after fetching cached responses with cookies
- Update session cookies after fetching cached responses with _redirects_ with cookies
- Add support for additional request parameter types that `aiohttp` accepts:
- Strings
- `(key, value)` sequences
- Non-`dict` `Mapping` objects
- Fix URL normalization for `MultiDict` objects with duplicate keys
- E.g., so `http://url.com?foo=bar&foo=baz` is cached separately from `http://url.com?foo=bar`
- Update `ignored_params` to also apply to headers (if `include_headers=True`)

- Fix compatibility with aiohttp 3.8

- Fix issue with request params duplicated from request URL
