Refactor marc_clean_serialize into separate functions

[shelleydoljack]

This function does two things but maybe in some cases we would only want one of them to happen. It removes the tags using the exluded tags list but also writes out marc to marcxml. It seems like the function should be split into two. We don't have a use case yet for it, but there might be a future need to exclude tags but not serialize to xml.
