Add select option for useQueries

[vadim-ch]

I propose to add select option for useQueries to compute values from several queries at the same time

And use it something like this:

export const useProgram = (id: string) => useQueries({
  queries: [programsListQuery(), featuresListQuery()],
  select: ([programs, features]) => {
    const program = programs.find((program) => program.id === id);
    const programFeatures = features.filter((feature) => feature.programId === id);

    return {
      ...program,
      features: programFeatures,
    };
  },
});

I think it would be very helpful

Hi 👋

The useQueries hook returns an array of queries. I think you could compose this differently by returning the interesting information from the custom hook instead of trying to use the select function. As an aside, the useQueries query options are almost identical to the useQuery query options so you could provide a select option for each query, although I don't think that's particularly helpful here.
