Nested eager loading with deleted

[pencasolutions]

Is your feature request related to a problem? Please describe.
Currently we cannot use a .withDeleted() on a nested eager load, this is causing an issue when trying to account for soft deleted items within a relationship.

Describe the solution you'd like
Something similar to:
Item1.query(on: req.db) .withSoftDeletesIncluded(\.$model)
Item1.query(on: req.db) .withDeleted(\.$model)

Describe alternatives you've considered
Currently I query separately rather than nesting so I can include soft deletes.
