Merge branch 'bnewbold-import-refactors' into 'master'

import refactors and deprecations

Some of these are from old stale branches (the datacite subject metadata patch), but most are from yesterday and today. Sort of a hodge-podge, but the general theme is getting around to deferred cleanups and refactors specific to importer code before making some behavioral changes.

The Datacite-specific stuff could use review here.

Remove unused/deprecated/dead code:

- cdl_dash_dat and wayback_static importers, which were for specific early example entities and have been superseded by other importers
- "extid map" sqlite3 feature from several importers, was only used for initial bulk imports (and maybe should not have been used)

Refactors:

- moved a number of large datastructures out of importer code and into a dedicated static file (`biblio_lookup_tables.py`). Didn't move all, just the ones that were either generic or very large (making it hard to read code)
- shuffled around relative imports and some function names ("clean_str" vs. "clean")

Some actual behavioral changes:

- remove some Datacite-specific license slugs
- stop trying to fix double-slashes in DOIs, that was causing more harm than help (some DOIs do actually have double-slashes!)
- remove some excess metadata from datacite 'extra' fields
