ES Modules broke the CLI? #199
Description
Invoking the CLI since 0.29.0 results in a runtime error due to the #!/usr/bin/env -S node -r esm shebang. I've reproduced the issues installing globally with npm i -g and installing in a project's node_modules for invocation via via node_modules/.bin/commonmark or npx commonmark.
Relevant Commit: 9bcf45b
I am not up-to-date on Node.js and ESM support, or this package's Node.js version compatibility contract.
I will poke around a bit now and try to see if I can introduce a test for CLI invocation.
