server: enable pyrp3 dependency for all platforms

[doronbehar]

No other machines should really use the server, and this dependency doesn't hurt any other platform that is used to test the server. This also helps a bit installing the server in an offline manner (#378), see also:

jazzband/pip-tools#1220

The restriction for pyrp3 is required for installing linien-server on other platforms for running the server with the --fake flag.

The restriction for pyrp3 is required for installing linien-server on other platforms for running the server with the --fake flag.

But @bleykauf I don't understand - you can run linien-server run --fake even if you have pyrp3 installed as well - what's wrong with including pyrp3 unconditionally?

The issue is that pyrp3 cannot be installed on Windows machines, at least not without additional requirements:

The issue is that pyrp3 cannot be installed on Windows machines, at least not without additional requirements:

OK I see, I also understand that when wishing to install linien-server on a Windows machine that would be an issue. However, if a Windows user really wants to work on the development of linien-server on a Windows machine and they don't have a MS Visual C++ environment setup, they can avoid installing pyrp3, and install all other dependencies manually and simply run:

python linien-server/linien_server/cli.py run --fake

Given that linien-common is installed, and all other pure Python dependencies are installed. Also, it should be possible to construct a python -m piptools compile command like I showed in #378 (comment) that would avoid installing pyrp3 on Windows. This is a command that should work on Bash (and hence not on Windows):

python -m pip download \
  --no-deps \
  /path/to/linien-repo/linien-server \
  --requirement <(python -m piptools compile \
    /path/to/linien-repo/linien-server/pyproject.toml \
    --output-file - 2>/dev/null | sed \
      -e 's/^\(pyrp3==2.0.1\)/#\0 is not available on for Windows.../g' \
