[libgpiod][PATCH 1/2] bindings: cxx: provide request_builder::set_output_values()

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

Implement a new method in the request_builder class that allows to set
output values at request-time by calling the set_output_values() method
of the internal line_config object.
