 You are not forced to use `applySnapshot(_:)` in combination with `FHDiffableDataSourceSection` array to apply snapshots to your `dataSource`. You can override the `applySnapshot(_:)` to change its behavior, create your own `applySnapshot()` method or do it manually as follows:

 ### init(layout:)
 
 I use a custom initializer for the `FHDiffableCollectionViewController` which is based on an enum. This contains a case for `UICollectionViewFlowLayout`, for `UICollectionViewCompositionalLayout`, for a custom `UICollectionViewLayout` or a default case. The default case creates a compositional layout which is only intended to be used for testing.
