This PR adds an
n_threadskeyword toSourceCatalogto compute the compiled per-source measurements (the isophotal moments and their errors, the segment pixel statistics, the windowed and quadratic centroids,perimeter, the Kron radii and photometry,circular_photometry, andflux_radius), and thus every property derived from them, using multiple threads. The sources are divided into chunks that are processed concurrently, producing results identical to the single-threaded computation.
