Pull request overview

This PR improves error handling for unsupported operating systems by raising a clear, user-friendly NotImplementedError at module import time instead of allowing the application to fail later with a cryptic error. This addresses issue #356, which requested better error messages when the library is imported on unsupported systems like Windows.

Changes:

• Added early validation check at import time in _sampling.py to detect unsupported operating systems
• Implemented a user-friendly error message with guidance to request support via GitHub issues
• Suppressed traceback for cleaner error presentation using sys.tracebacklimit = 0

Setting sys.tracebacklimit = 0 modifies global state that affects all future tracebacks in the Python process. While this is acceptable for this use case (since the program will terminate after raising the error), consider documenting this side effect with a comment. If someone were to catch this exception and continue execution, all subsequent tracebacks would be suppressed.

Suggested change

	if SYSTEM not in _SUPPORTED_SYSTEMS:
	if SYSTEM not in _SUPPORTED_SYSTEMS:
	# NOTE: This modifies global interpreter state and will suppress all subsequent
	# tracebacks in the current Python process. This is intentional here to avoid
	# noisy stack traces on unsupported platforms; if this exception is caught and
	# execution continues, traceback output will remain suppressed.
