perf: several optimizations for improving the performance of the engine (#540)
* ♻️ refactor: initialize & store the config & cache structs as a constant (#486)
- initializes & stores the config & cache structs as a static constant.
- Pass the config & cache structs as a static reference to all the
  functions handling their respective route.

*  perf: replace hashmaps with vectors for fetching & aggregating results (#486)
- replace hashmaps with vectors for fetching, collecting & aggregating results as it tends to be contigous & cache efficient data structure.
- refactor & redesign algorithms for fetching & aggregating results
  centered around vectors in aggregate function.

*  build: add the future crate (#486)

*  perf: use `futureunordered` for collecting results fetched from the tokio spawn tasks (#486)
- 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.

*  perf: initialize new async connections parallely using tokio spawn tasks (#486)

*  perf: initialize redis pipeline struct once with the default size of 3 (#486)

*  perf: reduce branch predictions by reducing conditional code branches (#486)

*  test(unit): provide unit test for the `get_safesearch_level` function (#486)

*  perf: reduce clones & use index based loop to improve search results filtering performance (#486)

* 🚨 fix(clippy): make clippy/format checks happy (#486)

* 🚨 fix(build): make the cargo build check happy (#486)

*  perf: reduce the amount of clones, to_owneds & to_strings (#486)

*  perf: use async crates & methods & make functions async (#486)

* 🔖 chore(release): bump the app version (#486)
