[Feature Request] Async support for REST API

[liblaf]

Currently, the Binance Python SDK relies on the synchronous requests library for its REST API operations. This makes it challenging to integrate with asynchronous Python applications and frameworks.

• Please consider adding support for async REST API operations to the SDK, such as by providing an async client or refactoring key functionality to use an async HTTP library (e.g., httpx, which supports both sync and async).
• This enhancement would greatly benefit developers who need high concurrency with Binance services but cannot use WebSocket.
• Maintaining backwards compatibility with synchronous usage would be ideal.

Thank you for considering this feature!
