Build me a TypeScript Node.js library for App Store Optimization analysis that works with both Google Play and the Apple App Store.

I want it to let me search apps, get app details, analyze a keyword, find similar apps, and generate keyword suggestions. It should also calculate useful ASO scores like keyword difficulty, traffic, market saturation, competitor strength, and keyword combinations. Please include a clean main class for the store specific API plus a separate analyzer helper for the more advanced calculations.

Make it feel production ready, with good error handling, request throttling, optional caching, and support for country, language, timeout, and other simple config options. Add types for the main inputs and outputs, and make sure it is easy to use from a small example script.

If you need current API details or behavior from related services, look them up online and use sensible defaults.
