This PR adds an
n_threadskeyword todeblend_sourcesandSourceFinderto deblend the sources using multiple threads. The sources are divided into chunks and processed concurrently, producing results identical to the single-threaded computation. The marker-building kernels release the GIL, as do the watershed and most of the array operations, so multithreading can significantly speed up deblending, especially for large sources.
