`NO_CACHE` failed to execute example program ntfsdir

Thanks for trying my project. Yes, using FULL_CACHE when declaring NtfsVolume will kill your memory (it takes about 25Go on my computer). Try use NO_CACHE.

You can also reduce MEMORY_BUFFER_SIZE in file-reader.cpp. It will take more time to read but cache will store less unused data.

Thanks for your report and for the fix. I didn't worked on this project for years. I will try to found some time to investigate.
