protobuf version issue #139
Description
After installing python packages in 'requirements.txt' then running python -m ankisyncd I get this error:
Traceback (most recent call last):

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates
Downgrading the protobuf package as directed does fix it but I'm not sure if that's the most appropriate solution or if I'm missing something?
