Issue 1906 no fits rdf mapping

[dannylamb]

GitHub Issue: Resolves Islandora/documentation#1906

What does this Pull Request do?

Adds an RDF mapping for FITS and configures the appropriate context to make indexing happen

How should this be tested?

• Go to a FITS media in your Islandora instance and check out its JSONLD. It should be pretty empty.
• Apply this PR and re-import the feature (or you could be surgical and just add the configs in this PR to your site using Drupal's config sync tools if you've customized your config significantly)
• Clear your cache
• Now go check out the JSONLD for a FITS file and it should be full of useful information
• BONUS POINTS: Check out the RDF in Fedora and confirm it's also full of useful information

The build failed because the RDF mappings presume we have the FITS Media type included in islandora_defaults, except they don't exist unless you have included the roblib/islandora_fits module. We either need to

• add roblib/islandora_fits to the composer.json and the islandora_defaults.info.yml OR
• move the RDF config to roblib/islandora_fits and use their install hook to add fites_technical_metadata to the context.context.all_media config.

Tested in our setup, and looks good. Thanks @dannylamb!
