[FEATURE]: Add support for fetching lib via URL

**Problem**

Currently we either need to provide the public package name or bundled output of npm.

Would be nice if we can download the npm package from any arbitrary URL.

**Usecase:**

- Use bundled library from Codesandbox CI
eg: `https://pkg.csb.dev/razorpay/blade/commit/3d845e9a/@razorpay/blade`
- This will also enable running this script inside a CI in future

The issue names no files, tests, or entry points. Start by locating the existing paths for public package names and bundled npm output, then trace where package input is handed to the analyzer. Done means an arbitrary URL, including the Codesandbox CI example, can be downloaded and analyzed in the same workflow.
