Do not use tensor tuple past sampler

A tuple list is not editable. You cannot add to remove, or dynamically (easily) rebuild it without knowing total tensors and catting them manually by code (which means a whole huge conditional block to handle every possible size in nodes).

After the ksampler, tensors should be converted to a simple `list` of tensors for post processing management. Otherwise you're limited to very basic tensor operations on the whole batch which severely diminishes the continuity of a node system.
