52-osc - Implement OSC 52 ; Interact with X11 clipboard

=head1 SYNOPSIS

   urxvt -pe 52-osc

=head1 DESCRIPTION

This extension implements OSC 52 for interacting with system clipboard

This is adapted from https://gist.github.com/ojroques/30e9ada6edd9226f9cc1d6776ece31cc
to use the actual system clipboard instead of the urxvt selection.
