chore(refactoring): Refactor/modernizations (#2345)

chore(refactoring): Refactor with modernization refactorings

* range over int
* replace interface{} with any
* replace common map operations with maps.Copy/maps.Clone
* simplifying loops with slices.Contains/ContainsFunc
* modernize benchmarks with b.Loop
* modernize tests with t.Context
* use fmt.Appendf
* range over strings.SplitSeq
* use new stdlib crypto/pbkdf2 package
