Reduce memory usage of adding tracks Significantly reduce the memory footprint of adding tracks to the playlist, by coalescing the NSString and NSData objects in the info dictionaries as they are being loaded in the background, into a common data set which will then be discarded when the whole job is completed.

// RedundantPlaylistDataStore.h

//
// Created by Christopher Snowhill on 2/16/22.
//
// This is designed primarily for the PlaylistEntry info loader, to prevent
// memory overrun due to redundant blobs of data being duplicated repeatedly
// until the list is fully loaded. This instance will be discarded after the
// info is loaded, freeing up hopefully way less memory afterward than now.

Deduplicate artwork using hashes Artwork deduplication should be done with hashes, not by full data comparison. This should be a lot faster loading artwork from files now, especially if the playlist already contains a lot of unique artwork. Signed-off-by: Christopher Snowhill <kode54@gmail.com>

Add a metadata loader cache Promote the Plugin Controller source file to Objective-C++, and add a simple data cache that holds on to requests for up to 5 seconds after their last access, for preventing spammed requests from hitting files over and over. This is apparently really relevant to the CUESheet reader and its embedded CUESheet handling, as that tends to reread the same file over and over as it populates the playlist with tracks. The nested reader can also lead to repeated reading even on files without CUESheets embedded. Signed-off-by: Christopher Snowhill <kode54@gmail.com>
