Used by the routines at sparkle_sound_and_draw and cycle_attribute_mem.

A burst of short blips whose pitches are read from the ROM at $1234, so the burst sounds random but is the same every time. The number of blips is the bottom five bits of the complemented type: fifteen for the first death sparkle (type 112), falling by one each frame as the sparkle runs down. Also used by cycle_colours_with_sound as each wanted charm goes into the cauldron.
