Scope collectionHQ extract to org unit + children

Enable collectionHQ extract functions to scope to a specified org
unit ID and that org unit's children. Specify a default org unit of
1 to closely reproduce previous behavior.

NOTE: Even with an org unit of 1, this work-in-progress changes
previous behavior due to requiring an asset.call_number with
owning_lib in scope. Previously ALL bibs were included.
