Switching to new ankiweb API (#7)

* anker/anki_proto: Add protobuf files for a new Anki API

Recently, ankiweb change it's API and this changed was drastic.
They moved from html forms and bare http-requests to Protobuf
communication and sending binary Protobuf structures over http.

These are the Protobuf files used by ankiweb I handcrafted from
the frontend.

* requirements.txt: add protobuf

The version is fixed to work with current python version.
I picked it up from the error:
```
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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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).

```

* setup.cfg: exclude *_pb2.py files from flake8

* Dockerfile: add protobuf-files generation

* anker: use new ankiweb's Protobuf API

* anker/bot/sticker_storage.py: add http requests timeout

* requirements.txt: remove unused beautifulsoup4 and lxml

* requirements/requirements-dev.txt: add types-protobuf

* tests/anki_api: skip tests and remove unused

* .gitignore: add *_pb2.py

* setup.cfg: fix mypy checks

* requirements/requirements-dev.txt: update some requirements

* Fix mypy issues

* .github/workflows/python-app.yml: generate protobuf files first
