[perl sdk 5.52] VILib.pm : sub add_options wrongly parses %opts [ also solution :) ]

So , as described upper , downloading the tar.gz version of the latest ( at the moment) Perl SDK 5.52 , when invoking

Opts::add_options(%a_hash) 
the %options are not actually updated because


if (!exists($options{$key} ) {

only checks if $options{$key} vas defined but not instantiated

so for me i had to also check for its "->" too, to not be null  ;
