Typical user cache directories are:

macOS: ~/Library/Caches/<AppName>

in the `CSIDL_LOCAL_APPDATA` directory. This is identical to the

non-roaming app data dir (the default returned by `user_data_dir`). Apps
|

typically put cache data somewhere *under* the given dir here. Some

examples:

|

...\Acme\SuperApp\Cache\1.0

OPINION: This function appends "Cache" to the `CSIDL_LOCAL_APPDATA` value.
