[CHORE] Setup cargo-release for automatic bump

[jeertmans]

Currently, I have to manually bump the versions and update the changelog on every release, which is error-prone. A good idea would be to use cargo-release instead.

I already configured it for another repository, so anyone willing to help can take a tool at it :-)

The important aspect is to update every places that refer to the current version.
