fix(logs): coloured logs (#465)

* refactor(logs): replace chalk by ansi-styles

* test(logs): fix the failing tests due to ansi styles

I was not able to disable or mock ansi-styles so instead I found a way to make the tests pass
it's not perfect but it's still nice because the logs will keep their trustful colour when running through the tests

* refactor(logs): simplify the syntax to colour the logs

* chore(rebase): update files due to rebase

* refactor(logger): reduce code duplication
