fix: response leak when using caching adapter and streaming

[Tasssadar]

Currently, this library breaks requests behavior, where the finalizer will close response if user forges to call close. Use WeakRefs to prevent this.

[Tasssadar]

When you assign a method like this, you're creating a circular reference to self, because when you normally call response._update_chunk_length, it actually creates the bound method on-the-fly, it's not set there all the time.

This SO response helped me understand it: https://stackoverflow.com/a/26158130

Good catch and fix. I would like to accept this. And I will wait for the inputs from @woodruffw

Thanks, makes sense to me as well. I appreciate the additional unit test!

Assuming nothing else comes up, I'll cut a release in the next day or so.

@woodruffw sorry for bothering, but any update?

[woodruffw]

Sorry for the delay; I've opened #350 to prep the release.
