Get an FTP Listing Entry's Size as a String

Demonstrates the Chilkat Ftp2.GetSizeStr method, which returns the size in bytes of a cached directory-listing entry as a decimal string. The only argument is a zero-based index.

Background: Returning the size as text sidesteps integer-width limits entirely, which is useful in languages without a convenient 64-bit type and whenever you only need to display or log the value. Parse the string when you need to do arithmetic on it; otherwise it is ready to print as-is.
