Remove logic for creating electronic materials

[starsplatter]

The presence of 981 should not cause an order to be treated as electronic, we should remove that logic.

I think I have this mostly done. There is still a section of code that reads 856 datafields. Then is adds eResource data to the instance record and holdings record. Should that be commented out or removed?

Let's comment it out.

Okay....the requesters_5-records_2021-03-11.mrc file actually contains electronic resources. Should that be removed from the repo or should we keep it around for testing that the app will reject records that are for e-resources.

I don't think they do. The have 856 fields but they are articles or descriptive links, not links to the resource.
