Crate filesize

Get the real on-disk size of a file, taking into account compression and sparse allocation.

On Unix this uses std::fs::symlink_metadata() and std::os::unix::fs::MetadataExt.

On Windows it uses GetCompressedFileSizeW().

Returns the logical size on platforms other than Unix and Windows.
