asyncio.get_event_loop() doesn't create a new loop since Python 3.14

This probably resolves #28
Discl: my understanding of asyncio is very limited, there may be a better way of solving this.

Pull Request Overview

This PR addresses a compatibility issue with Python 3.14 where asyncio.get_event_loop() no longer automatically creates a new event loop. The change updates the code to explicitly create new event loops using asyncio.new_event_loop() instead.

• Replaces asyncio.get_event_loop() with asyncio.new_event_loop() in test cases and documentation
• Ensures compatibility with Python 3.14's stricter event loop management

[Copilot]

When creating a new event loop with asyncio.new_event_loop(), it's recommended to also set it as the current event loop using asyncio.set_event_loop(self.my_loop) to ensure proper context for asyncio operations.

Suggested change

	self.my_loop = asyncio.new_event_loop()
	self.my_loop = asyncio.new_event_loop()
	asyncio.set_event_loop(self.my_loop)
