FT.AGGREGATE _ LOAD * is not supported

Description

I'm not sure if it counts as a bug or a half-implemented feature...

https://redis.io/commands/ft.aggregate/
If * is used as nargs, all attributes in a document are loaded.

I assume it is not supported – couldn't find any mention in issues or elsewhere.

Example: FT.AGGREGATE idx:user * LOAD * should return all fields of all indexed "user" documents.

await client.aggregate(`idx:user`, "*", {
  LOAD: "*", // causes TS error, does not work as JS as well
  // TS2345: Argument of type [string, string, {LOAD: "*";}] is not assignable to parameter of type
})

It seems Node-Redis supports only basic named fields like LOAD: "@email". It does not support load all functionality which is IMO necessary, for example, to implement cursor-based pagination.

await client.aggregate(`idx:user`, "*", {
  LOAD: "@email", 
}) // works fine

Update

As a temporary low-level solution it's possible to:

await client.sendCommand(["FT.AGGREGATE", "idx:user", "*", "LOAD", "*"])

Requires manual reply, manual JSON parsing, etc.

Start at the client.aggregate entry point and compare its LOAD @email handling with the raw sendCommand example for FT.AGGREGATE. Check how LOAD options are typed and serialized; done means LOAD: "*" is accepted by TypeScript and works like the documented Redis command without manual parsing.
