⚡ perf: use futureunordered for collecting results fetched from the tokio spawn tasks (#486)

Browse Source 
- using the `futureunordered` instead of vector for collecting results
  reduces the time it takes to fetch the results as the results do not
  need to come in specific order so any result that gets fetched first
  gets collected in the `futureunordered` type.
