feat: add whereNotHashedIds scope

[bensherred]

Overview

• I have performed a self review of my code
• I have made corresponding changes to the documentation
• I have commented my code, particularly in hard-to-understand areas
• I have added sufficient logging
• New and existing tests pass locally with my changes
• The code modified as part of this PR has been covered with tests

Problem statement

This package has a scope called whereHashedIds which allows us to get all models where the ids match the hashed ids. However, there are times where we need to get all records where the hashed id is not in the array.

Solution

This PR adds a new whereNotHashedIds scope.
