[rogalski]

Avoid dependency on python3-devel and pybind11 by using precompiled dependency.

@zafercavdar can we merge this please? i'm quite sure so much people doesn't use this because are struggling to install pybind11 on their systems

Hi, same here, I am stuck because of that, could you please merge it and publish a new version ?

Regards !

To anyone interested, I took the liberty of creating a new python lib : https://github.com/jgcb00/fasttext-langdetect-wheel

Will delete it when the merge goes through
