(Node.js) SFTP HardLink - Create a Hard Link using the hardlink@openssh.com Extension

Demonstrates how to create a hard link on the SFTP server using the hardlink@openssh.com extension. Note: This only works on servers supporting the hardlink@openssh.com extension.

Note: This example requires Chilkat v9.5.0.71 or greater.
