Describe the bug

Trying to run a different project jpterm and encountered the following traceback:

I've identified the problem to be coming from this line in your httpx_ws/_api.py:L14 file

httpx-ws/httpx_ws/_api.py

Line 14 in f0e4d4b

from httpcore.backends.base import AsyncNetworkStream, NetworkStream

Replacing

from httpcore.backends.base import AsyncNetworkStream, NetworkStream

with

from httpcore._backends.base import AsyncNetworkStream, NetworkStream

resolved the issue.

Since v0.17.3 use

from httpcore import AsyncNetworkStream, NetworkStream

instead of

from httpcore.backends.base import AsyncNetworkStream, NetworkStream

ref: https://github.com/encode/httpcore/blob/master/CHANGELOG.md#0173-5th-july-2023

[saforem2]

fixed and updated in #36

Thank you @saforem2 for raising this and @wimglenn for pointing out the fix :) That's the risk when we rely on private API 😅
