Python bindings now have their own setup.py script and can be built separately from the rest of the code-base. Let's decouple the python package version from libgpiod API (but let's keep a module attribute containing the API version) by introducing a version.py submodule that can be executed by the setup.py script. This way we have a single canonical place defining the version number. Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
