Adds quiet option

[steveruizok]

This PR adds a -q --quiet option to suppress console logs. If a user provides both quiet and verbose flags, the verbose flag will win.

[steveruizok]

Added an example project for testing the CLI.

cd example
yarn build
yarn build -q
yarn build -v

[steveruizok]

Added a files option to the package.json to prevent publishing the src folder.

Make sure to get the README options updated.

I don't want examples/tsconfig.types.cjs.json and examples/tsconfig.types.esm.json erased as they are what a user would need to export a package with both CommonJs and ESM. This is explained here on the README. Can we make sure those stay and update the README is their path has changed?

[jonkwheeler]

Give me a bit here and I'll test this out. Thanks!

[jonkwheeler]

Just following up. I was away for awhile getting hitched. Settling back in.

Actually, I changed my mind. If you install 0.0.8 there will only be 1 confirmation log, and that's it.
