This is the initial check-in for a custom module to migrating ArchivesSpace EAD into drupal media entities

Looking good. I have some changes to avoid hardcoding the path.

Rather than use a directory as the parameter, use the media bundle as the parameter and read the configured directory.

Something like:

    // Fetch the media type bundle from the config
    if (isset($configuration['constants']['media_bundle'])) {
      // Load the field config for field_media_file on your media bundle
      $field_config = \Drupal::entityTypeManager()
        ->getStorage('field_config')
        ->load('media.findingaid.field_media_file');

      $file_directory = $field_config->getSetting('file_directory');

      // Resolve tokens — pass a context entity if tokens depend on the entity
      $token = \Drupal::token();
      $resolved = $token->replace($file_directory, [], ['clear' => TRUE]);

      $scheme = $field_config->getSetting('uri_scheme') ?? 'public';

      $this->eadXmlDir = $scheme . '://' . trim($resolved, '/') . '/' . $value;
    } else {
      $this->eadXmlDir = self::SAVE_BASE_URI;
    }

Rather than code the directory here, let's use the Media bundle as the setting, and fetch the directory from there:

Something like

  constants:
    media_bundle: 'findingaid'

This constant should also be used in the destination.

Then, see ASpaceFileSource.

"Migrates EAD files..."

Put a dummy value in here, if a value is even needed at all. We don't need folks trying admin:admin against our site, even if it won't work.

Add a Prerequisites section. This probably includes Islandora? And certainly includes the Media Entity bundle we've hardcoded above (and the fields we hardcode from it).
