Convenient Pagination API, Browser Support, Missing API fields

[pyrogenic]

Several additions to Discojs that I've accumulated over the years building Elephant. It's a browser-based tool to manage a Discogs collection and store listings. (source)

• Add an all API to Discojs that retrieves all pages of a paginated endpoint given the first page:

  function updateCollection() {
  return client.listItemsInFolder(0, undefined, {
    perPage: 100,
  }).then(((r) => client.all("releases", r, addToCollection)), setError);
  }

• Add a model for the error format used by Discogs to allow better error reporting
• Add a few missing fields to various responses (notes to FolderReleases, name to Artist, avatar_url to User)
• Fill out the model for marketplace listings, which did not include any of the owner-only fields
• Fix nesting of the model for per-track information
• Add the option to provide a ResultCache which may be used to skip retrieving results multiple times. (My app stores GET responses using IndexedDB.)
• Tweak the package scripts to work on Windows (I develop on several platforms)

Happy to make changes to allow the PR to be accepted.

@pyrogenic Sorry for missing this one, and thanks for all the improvements! Would it be possible to split this PR into multiple ones so it'd be easier to review? Happy to help!

@aknorw thanks so much for taking the time to review, and sorry for the delayed response. I'll take a closer look outside work hours!

... and apologies for throwing a couple years of tweaks up in a single PR!
