Add ``--children`` flag to :mod:`profiling.sampling` CLI to automatically
profile child processes spawned by the target. When enabled, the profiler
monitors for new Python subprocesses and profiles each one separately,
writing results to individual output files. This is useful for profiling
applications that use :mod:`multiprocessing`, :class:`~concurrent.futures.ProcessPoolExecutor`,
or other subprocess-based parallelism. Patch by Pablo Galindo.
