Built-in Big Number/Decimal API

[ThallesP]

JavaScript's current big number/decimal landscape is diverse, with developers relying on third-party libraries like big.js and decimal.js. These libraries, implemented in JavaScript, introduce performance bottlenecks, especially in computationally intensive applications like financial calculations and scientific simulations. The variety of libraries also forces developers to choose between different APIs and features.

Proposed Solution:

Implement a native, performant, and unified API for big numbers/decimals in Bun.

Benefits:

• Performance boost
• Simplified development
• Improved accuracy/consistency
• Reduced cognitive load
• No External Dependencies

And also, dealing with JSON that has big numbers can be a real headache. If Bun could make that easier, it would be a huge win!
