Zstandard frames: the trailing zero padding is trimmed once, not looked
for again before each frame, and at most 4096 frames are read (more is
damaged data). A `]` finds its `[` from a list of where they are rather
than by scanning the operand stack back. Images are read up to 32
million pixels. Tests: thousands of tiny frames, and hundreds of
thousands of unmatched brackets, read in one pass.
