engine: D4R_M_DUMP also writes the reconstruction's outputs

d4r-m's D4R_M_DUMP now also writes what the reconstruction (post_m.comp)
writes: the history (hist, RGBA16F at the reconstruction resolution), its
half-resolution mean (half, RGBA32F) and the packed 11-11-10 image the
downsample reads (packed). The presented image is the packed one filtered and
rounded again, so a change in the history shows up there a frame later, if at
all; the dump shows it in the frame it happens.
