Integration Request: Add ThriveStack Plugin Support to Analytics Package

Hello @DavidWells,

I would like to propose integrating a new plugin for the analytics (https://www.npmjs.com/package/analytics) package that connects it with ThriveStack (https://thrivestack.ai/), an AI-powered growth intelligence platform designed to unify marketing, product, and revenue analytics.

About the ThriveStack Plugin
The ThriveStack plugin enables seamless tracking of user behavior and marketing/product analytics by integrating ThriveStack’s powerful capabilities directly into the analytics ecosystem.

Key Features:

Requires only two critical configuration parameters: apiKey (ThriveStack API key) and source (either 'marketing' or 'product').

Supports automatic event tracking for clicks and events.
Respects user privacy settings including Do Not Track and consent management.
Supports event batching to optimize network requests.
Compatible with all modern browsers including IE11 (with polyfills).
Implements core Analytics API methods: page, track, identify, and reset.
Provides additional custom methods like groupIdentify, setConsent, and debug utilities.

I kindly request your consideration to include this plugin as part of the official analytics plugins ecosystem or guidance on how best to collaborate for smooth integration.

Please let me know if you need any further details or a pull request with the implementation.

Thank you for your time and support!

No files, tests, or plugin entry points are named; begin by reviewing the analytics package's existing plugin ecosystem and integration conventions. Done should include ThriveStack support with apiKey and source configuration, the listed tracking and privacy behavior, batching, core API methods, and the requested custom methods.
