Pillow JPEG2000 tiled decode retains a growing scratch buffer and can be used for denial of service

Summary src/libImaging/Jpeg2KDecode.c:853 accumulates totalcomponentwidth across every tile in a JPEG2000 image instead of recomputing it per tile. That accumulated value is then used in the tilebytes calculation at src/libImaging/Jpeg2KDecode.c:868, which can make the decoder grow state-buffer v...
