Expand docs note for async custom handler responses (#1916)

* Expand note for async custom handler responses

Custom response handlers need to run `response.read()` before they can read the content of the response. However when using an AsyncClient this will produce an error of `RuntimeError: Attempted to call a sync iterator on an async stream.`. Took me some digging to figure out I just needed to use `response.aread()` here instead of `response.read()` so figured I would an MR with an expansion on the note for anyone else.

Stricter enforcement of either 'with httpx.Client() as client' or 'client = httpx.Client()' lifespan styles. (#1800)

Add a network pytest mark for tests that use the network (#1669)

* Add a network pytest mark for tests that use the network

Sometimes it's useful to have the tests that use the network
marked so they can be skipped easily when we know the network
is not available.

This is useful for example on SUSE and openSUSE's build servers.
When building the httpx packages (actually, any package in the
distribution) the network is disabled so we can assure
reproducible builds (among other benefits). With this mark, it's
easier to skip tests that can not succeed.

* Add a better explanation for the network marker

Fix JSON wrong encoding tests on big endian platforms (#1781)

Fix test_json_without_specified_encoding_*_error tests on big endian
platforms.  The tests wrongly assume that data encoded as "utf-32-be"
can not be decoded as "utf-32".  This is true on little endian platforms
but on big endian platforms "utf-32" is equivalent to "utf-32-be".
To avoid the problem, explicitly decode as "utf-32-le", as this should
trigger the expected exception independently of platform's endianness.
