[FR] Use NER to extract named entities, and create nodes for them

[njncalub]

Description

Extract Named Entities such as Characters, Skills, Spells, Classes, Locations, Items, etc, and create Nodes for them.

Motivation

This will allow us to link together the existing nodes and create more essential relationships.

Suggested Implementation

• Manually annotate the contents of existing Chapters using https://tecoholic.github.io/ner-annotator/
• Use spaCy and create the training models
• Create a service that will allow one to extract the named entities from a new Chapter
• After getting the entities, cross-reference with the data from the wiki

Alternate Implementations

• Manually extract the data from the wiki and use that as the reference
