Cross-platform encoding compatibility fix

Problem

The current encoding implementation using multiprocessing.Pool fails on macOS due to its different process forking behavior. This affects users trying to run the encoding function on macOS systems.

Solution

Implemented OS-specific parallel processing:

Uses ThreadPoolExecutor for macOS environments
Retains multiprocessing.Pool for other operating systems (Linux/Windows)

Technical Details

macOS handles process forking differently ("copy-on-write"), causing issues with multiprocessing.Pool
ThreadPoolExecutor provides a more reliable parallel processing solution for macOS
Added OS detection using platform.system() to automatically choose the appropriate method

Result after fix:
