fix(import): enable compatibility between ES modules and CommonJS for ical.jsRenamed ical.js to ical.cjs to explicitly mark it as a CommonJS module and used `createRequire` to import it into the ES module project. This resolves module system conflicts and ensures seamless integration without modifying ical.js content.
