requiredError is inadequate

[arnab]

When you specify required attributes:

const options = {
  required: {
    episodes: ["title", "pubDate"],
  },
};
const feedData = await podcastFeedParser.getPodcastFromURL(feedUrl, options);

... and the feed is missing some of the required fields:

Error: One or more required values are missing from feed.
    at Object.<anonymous> (/Users/arnab/code/projects/orcalabs/podcast-directory-management-tools/functions/node_modules/podcast-feed-parser/index.js:6:21)

It would be nice to get some more information from the error: such as which field specifically was missing.
