Prevents ffmpeg/ffprobe from erroring out when reading an HEIF that contains multiple hvcC thumbnails (e.g. from a Nikon Z6III camera). Before, move_read_iref_thmb() would always override the stored thmb_item_id in the MOVContext with each new read thumbnail, causing a stream and item_id mismatch later in mov_parse_heif_items(), resulting in the "HEIF thumbnail doesn't reference a stream" error message. To solve this, - Turn thmb_item_id into an array of IDs because multiple thumbnails can exist - Change check in mov_parse_heif_items() to compare against all stored thumbnail IDs to see if any item missing a stream is in the list of thumbnail IDs.
