Allow enabling and disabling lines from sequences

This allows two arguments to be passed to setup_hlt1_node from a sequence, enabled_lines and disabled_lines which are each a list of strings (line names or regexes). enabled_lines defaults to [r'.*?'] so that if it is not changed all lines already in the sequence will be kept. If it is replaced, that list will be used instead. For example, running with enabled_lines=["Hlt1DisplacedDielectron"] will cause only Hlt1DisplacedDielectron to run. disabled_lines defaults to [] so that if it is not set no lines will be removed. If it is changed, that line will not run. So for example, if enabled_lines=["Hlt1DisplacedDielectron","Hlt1KsToPiPi"] and disabled_lines=["Hlt1KsToPiPi"] then only Hlt1DisplacedDielectron will run.
