🚀 The feature

We should update the current build configuration to a more modern one:

• instead of requirements files and a large setup.py use pyproject.toml instead
• for some reasons i would suggest to setup depend-a-bot to tackle some dependency issues and keep it actual

@frgfm i would assign this one to you :)
Is that ok for you ?

Motivation, pitch

better dependencies handling
reduce the amount of configuration specific files
hold dependencies up to date
