return exit code 1 if test failed (for use in test pipelines)

Hi Mario,

Thanks for publishing this checker!

I would be great if the script returned an exit code != 0 on failure.
Then I could add it to my automated test pipelines to verify no links in readmes, source comments etc. are broken.

Hi Fabian, nice to hear from you and thanks for submitting this PR :)

This was an one-day project of mine, I will hopefully add some tests and maybe a GitHub action soon so that this is even better suited for productive use.

Merged and bumped the version to 0.1.1 https://pypi.org/project/blinkcheck/#history

Great! Thanks for the quick merge and release :)
