Use cosmiconfig so users can use whatever config file extension they want

[felipecrs]

With cosmiconfig we could automatically load the configuration file from whatever supported file, such as:

• a package.json property
• a JSON or YAML, extensionless "rc file"
• an "rc file" with the extensions .json, .yaml, .yml, .js, or .cjs
• a .config.js or .config.cjs CommonJS module

I'm personally looking for a .czrc.json, so my VSCode can automatically detect it as JSON.

Nonetheless, this would reduce a lot of code from this repo.

My use case: I want to use .js to be able to import emojis from other file (my semantic-release and commitlint configs also import from there).

Just found out about lilconfig which has the parts of cosmiconfig that matter and zero dependencies.

I'm looking at this today.
