Add Wikipedia article citations to solr to find well-referenced books

### Problem

Cool find: "Wikipedia Citations: A comprehensive dataset of citations with identifiers extracted from English Wikipedia" https://arxiv.org/abs/2007.07022

> A total of 29.3M citations were extracted from 6.1M English Wikipedia articles as of May 2020, and classified as being to books, journal articles or Web contents. We were thus able to extract 4.0M citations to scholarly publications with known identifiers -- including DOI, PMC, PMID, and ISBN -- and further equip an extra 261K citations with DOIs from Crossref.

The data is freely available here! https://zenodo.org/records/3940692 This would be a cool thing to do an intersection with to see how many of these books are digitized. Or perhaps to include in our solr so we can sort by wikipedia citations/show "Wikipedia articles that reference this book"!

This would be a great way to find impactful books to add to our collection as well.

The fellow task would affectively be converting the data set to something like:
| Open Library Edition | Wikipedia Page |
With the big task being needing to resolve the identifiers to the open library edition, if one exists.
And then we can use that during full/live indexing to have that in solr! Then we can render it on the books page, and have it power things like sorting :slightly_smiling_face:
I couldn't help myself I played around with the data a bit :smile: It's super well structured and easy to use! (Also TIL about parquet files!): https://colab.research.google.com/drive/1JDY2RQHNJdfyoDb9D4LjowyOHS41woMW#scrollTo=ReImWwrqZEUm
This is just one of the 200 "shards" of the dataset! And 11158 have an identifier we can use to intersect with Open Library. If that scales, that'll be ~2.23 million things we can check against Open Library. Best strategy would likely be to load the Open Library editions dump data into a sqlite table, extract/index/normalize the identifiers we care about, load the 2.23 million parquet subset into another table, index/normalize the same identifiers, and then do a JOIN between the two tables, and dump the results into a new sqlite file. We can then use that file to load the data into solr.
