Fix leak of dispatch queues during setup. We don’t need to retain the queue after calling dispatch_queue_create because it already has a retain count of 1.
Fix some leaks when using / changing video filters.

Also, we don’t need to check for null before calling free. From the C standard, "If ptr is a null pointer, no action occurs".

Add PSP Serial Lookup for Compressed ISO (CSO)
Rename md5ChunkSize to HASH_READ_CHUNK_SIZE and remove the unused crc32ChunkSize as the same read chunk is used for both hashes. Increase the chunk size from 10KB to 32KB. Optimize CRC32 inner loop to avoid calling the length message for each byte. Together these changes reduce total hash calculation time by about 20% when reading from an SSD.
