A 'CSS reset' for TypeScript, improving types for common JavaScript API's

Without ts-reset:

• 🚨 .json (in fetch) and JSON.parse both return any
• 🤦 .filter(Boolean) doesn't behave how you expect
• 😡 array.includes often breaks on readonly arrays

ts-reset smooths over these hard edges, just like a CSS reset does in the browser.

With ts-reset:

• 👍 .json (in fetch) and JSON.parse both return unknown
• ✅ .filter(Boolean) behaves EXACTLY how you expect
• 🥹 array.includes is widened to be more ergonomic
• 🚀 And several more changes!
