ProjectTo recursion

[CaptTwigg]

``Continuation of IQueryable ProjectTo + other ideas.
The current ProjectTo implementation is working as expected for non-recursive mapping

While testing I found that having recursive BundleMember in my bundle would freeze Visual Studio and make it crash, but ideally there should be a way to specify nested properties to also have depth level.

Attribute idea, have the name of the property and depth level, maybe even throw an error if its not given.

public static partial class Mapper
{
    [RecursionDepth(nameof(BundleMetadata.ChildBundle), depth: 1)]
    public static partial IQueryable<BundleMetadata> ProjectToDto(this IQueryable<Bundle> q);
}
