add CRUD operations for managing licenses with CLI

[capsulecorplab]

e.g., CLI should be able to compile all licenses in a project into a single string under license field in package.json

{
    "license": "(CC-BY-4.0 AND MIT)"
}

Format should conform to https://spdx.github.io/spdx-spec/v2.3/SPDX-license-expressions/ and https://docs.npmjs.com/cli/v10/configuring-npm/package-json#license
