Normalize filename on APFS

On ZFS, -O normalization=formD enables normalization whenever two file names are compared on the file system. On APFS, it is built-in and always default.

However, when diff-ing list of files from two file systems, given that filenames are always stored unmodified, there may be normalization incensistencies that turn into false positives in diff output.

Use normalizeFolderByRef --srcDir <src> --dstDir <dst> to make folder names in dst match that of the src.

macOS (ZFS) Command Output Test

• find . -name '*.tak' is not normalized.
• ls is not normalized.
• ls *.tak in zsh is normalized.
• echo * in zsh is normalized.

It appears that glob expansion in zsh normalizes the arguments.

FLAC integrity check

Run flac-check.sh in the directory to check.

Transcode to AAC

Run transcode-aac-at.sh <targetDir> on macOS to transcode lossless formats into .aac files.
