LP1940662: Add a --pipe option to marc_export

Add a --pipe option to marc_export to force reading of record ids from
standard input when one or more of the --library, or --descendants
options are used.  This permits more flexibility when exporting
records with holdings for given libraries or subsets of a collection.

It is an error to specify the --all or --since and --pipe options in
the same command line.
