oemof.solph tag on dev not correct?

[MaGering]

Current oemof.solph version on dev to does not seem to be quite right. This may not have been noticed when installing via pip. However, Poetry installs a different solph version in oemof-B3.

I'm a bit confused myself. In the setup.py it says here version="0.5.2dev1",. Is pip following this version or the tag name? In any case, Poetry is clearly following the tag name. I just tried this with the branch fix/solph-version-on-dev. And with this branch the correct version of solph is installed in oemof-B3.

@nailend @henhuy could you have a look?

Pip is looking at pypi for the version number. See here.

Tags are only checked when you install from github with
pip install git+https://github.com/...@v0.5.2.dev

Somehow I must have overseen the "."
