Niquests

-------------------

**Fixed**
- Restoring the state of `AsyncSession` through pickle.
- Typing definition for query parameter not accepting `None` as values. (193)
- Overload incorrect definition for `AsyncSession::get`. (192)

**Added**
- Support for `PathLike` objects for `verify` parameter when passing a ca bundle path. (194)
- Caching and restoring OCSP state through pickling `Session` or `AsyncSession`.
- Caching and restoring QUIC known compatible hosts through pickling `Session` or `AsyncSession`.
- Shortcut convenient access to `Retry` and `Timeout` configuration objects in top-level import.

-------------------

**Fixed**
- Invoking ``niquests`` in more than one event loop, even if no loop concurrence occurs. (190)
The faulty part was the shared OCSP cache that was automatically bound the first event loop and
could not be shared across more than one loop. Keep in mind that Niquests async is task safe within
a single event loop. Sharing a single AsyncSession across more than one event loop is unpredictable.
We've waived that limitation by binding the ocsp cache to a single `Session`. (both sync & async)
- Undesirable ``socket.timeout`` error coming from the ocsp checker when running Python < 3.9.

-------------------

**Fixed**
- Static type checker getting confused around ``AsyncSession`` and attached overloads (``AsyncResponse`` or ``Response``). (185)

**Changed**
- Default keepalive (HTTP/2, and HTTP/3) changed to 1 hour. In conformance with urllib3-future.

**Removed**
- Automatic resolution of pending lazy responses if there are too many of them.
Previously, we hardcoded a limit of 128 * NUM_CONN_POOL maximum inflight (aka. unresolved/lazy) response.
This was unrealistic due to a number of factors like (but not limited to):
A) remote peers can choose at will the max streams.
B) we can have multiple pool with multiple (varying) max capacities.
C) retrieving max streams per pool per conn is a very costly procedure (in terms of performance).
We will revisit this later on. You still can set ``max_in_flight_multiplexed`` in your ``HTTPAdapter`` to
restore this broken behavior.

-------------------

**Fixed**
- SSE request block IO by default. Integrate better with urllib3-future new SSE web extension.
- Passing a list instead of tuple for multipart file upload ends in failure.

**Changed**
- urllib3-future lower bound version is raised to 2.12.900 to ensure built-in support for SSE.
- help script now yield if websocket extra is present and actual version.
- exception raised when no adapter were found now include a hint when the intent was websocket and extra isn't installed.

-------------------

**Fixed**
- async version of ``iter_line``. (182)

-------------------

**Added**
- base_url parameter to `niquests.Session` or `niquests.AsyncSession`. automatically prefix every request emitted with it. (179)

**Fixed**
- warning about coroutine method 'aclose' of 'AsyncSession.resolve_redirects' was never awaited.
