Feature request: scopy for duplicating file on remote (cmd_scopy)

[forfin]

scopy is smbclient cli command for duplicating file on remote with server-side copy calls.

From: https://www.samba.org/samba/docs/current/man-html/smbclient.1.html

scopy <source filename> <destination filename>
Attempt to copy a file on the server using the most efficient server-side copy calls. Falls back to using read then write if server doesn't support server-side copy.

Would be nice if libsmbclient-php can replicate smbclient scopy command.
