Factor the classes which do the work into a new "runner" package. This package has a core module where ZephyrBinaryRunner and common helpers will live, and one file per subclass / runner front-end. The top-level script, zephyr_flash_debug.py, still exists, but just delegates its work to the core. Signed-off-by: Marti Bolivar <marti.bolivar@linaro.org>
