 * ### Option Discovery
 *
 * Since plugins commonly add custom options, and TypeDoc does not permit options which have
 * not been declared to be set, options must be read twice. The first time options are read,
 * a noop logger is passed so that any errors are ignored. Then, after loading plugins, options
 * are read again, this time with the logger specified by the application.
 *
 * Options are read in a specific order.
 * 1. argv (0) - Must be read first since it should change the files read when
 *    passing --options or --tsconfig.
 * 2. typedoc-json (100) - Read next so that it can specify the tsconfig.json file to read.
 * 3. tsconfig-json (200) - Last config file reader, cannot specify the typedoc.json file to read.
 * 4. argv (300) - Read argv again since any options set there should override those set in config
 *    files.
