Improve docstrings in PyLoadAPI class

[tr4nt0r]

Enhanced docstrings for methods in the PyLoadAPI class to provide clear descriptions of their functionalities, return types, raised exceptions, and usage examples. Each method now includes detailed explanations of its purpose, what it returns, and the specific exceptions it may raise during operation. These updates improve code readability and facilitate easier maintenance and usage of the pyload_api module.

Changes include:

• Added or improved docstrings for methods: get_status, pause, unpause, toggle_pause, stop_all_downloads, restart_failed, toggle_reconnect, delete_finished, restart, version, and free_space.
• Ensured consistency and clarity in docstring formatting and content.

These updates adhere to numpy style for documenting Python code.
