Get an FTP Listing Entry's Size (32-bit)

Demonstrates the Chilkat Ftp2.GetSize method, which returns the size in bytes of a cached directory-listing entry as a 32-bit integer. The only argument is a zero-based index. It returns -1 when the index is invalid or the size is unavailable.

Background: The size comes from the cached listing, so reading it for every entry costs no extra round trips. A 32-bit result cannot represent files past about 2 GB, so use GetSize64 (or GetSizeStr) when large files are possible. Directories often report no meaningful size and come back as -1, which is why the -1 case is worth handling rather than printing blindly.
