Add Authentication via Cookies Support

I have added a new method __create_authenticated_session that enables creating authenticated TikTok sessions using authentication cookies. This method is internally used by create_authenticated_sessions to create multiple authenticated sessions.

Feature Details

The method accepts authentication cookies as a string in standard HTTP cookie format: key1=value1;key2=value2

Usage Example

from TikTokApi import TikTokApi
import asyncio
import os

api = TikTokApi()
    try:
        await api.create_authenticated_sessions(
            auth_cookies=auth_cookies,
            proxies=[proxy_config],
            num_sessions=1,
            sleep_after=0.5,
            headless=True,
            timeout=30000,
            browser=os.getenv("TIKTOK_BROWSER", "chromium"),
        )

Benefits

This functionality is particularly useful for:

• Accessing content restricted to logged-in users
• Interacting with TikTok as an authenticated user
• Bypassing certain limitations of unauthenticated requests

How to Get Authentication Cookies

Authentication cookies can be obtained by logging into TikTok through a web browser and exporting the session cookies.

Implementation Details

• Maintains compatibility with the existing API
• Follows the project's session management best practices
• Handles cookie parsing and session creation seamlessly
• Supports all existing session parameters (proxies, timeouts, etc.)

I've made sure to maintain the existing code structure and follow the project's conventions. The implementation is fully compatible with the current session management system.

Since users can attach cookies in the current code I think users can just do this on their side before calling create_sessions. If there's some other justification that this should be in the library let me know!
