docs: Takes a functional interface that throws an exception and returns a {@link Function} that deals with that exception by
  wrapping in a runtime exception. Useful for APIs that use the standard Java functional interfaces that don't throw checked
  exceptions.
  
  @param unsafeFunc Functional interface that throws checked exception.
  @param <T>        Input
  @param <R>        Output
  @return New {@link Function} that handles checked exception.
