This builds on top of PR #11 (and fixes #10) such that the CLI can now read from:
A file, given as file name argument (previously existing)
Any contents given as an argument (courtesy of @marccampbell)
stdin, either piped to the bin or entered when bin is executed without any arguments
This PR also allows this package to be installed globally (
npm i -g dockerfilelint
) and run as the executable bindockerfilelint
(can't believe I didn't notice this before).Since this PR changes how the bin behaves when no arguments are given, it should probably constitute a semver major bump.
