Chat with non-embedding db

[CahidArda]

Fixes two functionality for usage with non-embedding Vector Index:

• It was only possible to upsert without data. Vectors without data are not usable in chat. Now it's possible to pass a text with your embedding:

  await ragChat.context.addMany([
  {
  id: 1,
  type: "embedding",
  data: [1, 1, 0],
  text: "first embedding", // NEW
  options: { namespace },
  },
  {
  id: 2,
  type: "embedding",
  data: [1, 0, 1],
  text: "second embedding", // NEW
  options: { namespace },
  },
  ]);

  text is added to the data field of the index.

• adding embedding option in chat to make it possible to query a non-embedding index with your own embedding

  await ragChat.chat("hello world!", {
  embedding: [0, 0, 0.5], // NEW
  onContextFetched,
  namespace,
  });

Fixes

index.addMany is fixed with Promise.all
