Extend ILifetimeSelector with a new WithLifetime method that acepts a Func<Type, ServiceLifetime> parameter to map implementation type to service lifetime

Hello,

Thanks for the great library. One limitation currently stops be from fully adopting it in the project currently I work on (or maybe I am missing something and don't know how to do it).

Would you consider extending the ILifetimeSelector with a new WithLifetime method that accepts a Func<Type, ServiceLifetime> parameter, i.e. a function that maps an implementation type to a service lifetime?
This will allow registering services marked with a marker interface IAppService, but that have different lifetimes, something like this:

services.Scan(typeSourceSelector =>
{
    var assemblies = typeof(IAppService).Assembly;

    var serviceTypeSelector = typeSourceSelector
        .FromAssemblies(assemblies)
        .AddClasses(x => x.AssignableTo(typeof(IAppService)))
        .AsSelfWithInterfaces(x => typeof(IAppService).IsAssignableFrom(x) && typeof(IAppService) != x)
        .WithLifetime(implementationType => GetServiceLifeTime(implementationType));
});

Thanks
