Subject: [PATCH] add missing annotation to PyCounter.__call__

This patch annotates the `__call__` method of `PyCounter` in example: callable
objects with `#[args(args="*", kwargs="**")]`. Without it (at least in PyO3
0.15.0) the example fails with `TypeError: counter.__call__() missing 1
required positional argument: 'args'`.
