Setup Delayed::Job and create job. Resolves #23.

- Sets up Delayed::Job - Create a job to populated wasapi_files table from Archive-It WASAPI endpoint - Modify schema to handle large integers for `size` field - tweak RuboCop config to deal with new code. We should come back around and clean this up
