Enhanced Python Connector Distribution

Current State:
The existing Python connector wraps the C/C++ connector, delivering optimal performance for Python applications. However, this approach has limitations:

• Requires pre-installation of the C/C++ connector before running pip install
• Only supports CPython implementations

Objective:
This task aims to provide multiple installation options to accommodate different use cases:

1. Native implementation – Pure Python solution with broader compatibility across Python variants, though with reduced performance
2. C/C++ wrapper – Maintains the current high-performance approach
3. Wheel distribution – Pre-compiled C/C++ binaries that eliminate the need for local C/C++ connector installation

Installation Options:
Users will be able to choose their preferred installation method:

• pip install mariadb → Native pure Python implementation
• pip install mariadb[c] → C/C++ wrapper (current approach)
• pip install mariadb[binary] → Pre-compiled binaries for common operating systems

Additional Enhancement:
The connection pool package will be implemented in pure Python to ensure compatibility across all Python implementations. Users can combine installation options, for example:

pip install mariadb[c,pool] → C/C++ wrapper with connection pool support
