Slim down configuration
In some places we always use a Dense network, we can drop the class_path stuff and just provide directly the dense config. A similar appraoch is taken for the init_nets. The downside of this is that we loose the jsonargparse type checking, but in practice I don't think that is so bad since it gave quite confusing errors anyway.
Other things
- automatically configure init net input sizes from the variables in the
data:block. - some general config claenup.
