Unable to upload chunked big file using requests python library.

[Ph0tonic]

Describe the bug
I am trying to upload big files to this webdav server by using requests library. Other available libraries are not compatible with the way I receive the stream of data. However, the webdav server hangs forever and do not respond.

To Reproducexx
Steps to reproduce the behavior:

1. Launch a webdav server wsgidav --host=127.0.0.1 --port=31102 --root=/tmp --auth=anonymous
2. Generate a big file dd if=/dev/random of=data_big bs=1M count=100
3. Upload it to the webdav server

import requests
def generate():
    with open("data","rb") as f:
       while r:=f.read(1024**2):
          yield r
requests.put("http://127.0.0.1:31102/data", data=generate())

4. The upload hangs forever

Expected behavior

A working upload of the file.

Hello,
Any plan plan to release a new official version including this fix ?
For now, I am still using my fork but I would love to use the official one.
Thanks
