Struct SplitFileSystem 

pub struct SplitFileSystem<FS: RawFileSystem> { /* private fields */ }

A filesystem that splits files into clusters.

A cluster contains cluster_size blocks. When cluster_size is large enough, this filesystem is equivalent to the underlying filesystem.

Lower cluster_size implies better file size obfuscation, but also a higher overhead (both performance and storage).
