Single thread multiple timeout handler

C++ Standard: C++20 (uses <semaphore>)

This mini-library can handle arbitrary number of timeouts (measured in milliseconds) using a single thread, which always sleeps and wakes up only when some timeout expired.

Simple and easily modifyable library with thread-safety and all sleeping logic taken care of. Configure & forget.

Useful properties:

• Uses externally provided memory for arbitrary number of timeouts
• Single expiry timeouts or repeating timeouts
• Single thread handles all timeouts, always sleeps between timeout events
• Was originally designed to handle all TCP connection timeouts using a single thread
