Add workflows helper functions for sparse data

[EmilHvitfeldt]

What we need is a set of functions that that can help determine whether a recipe with sparse supporting steps should handle them as sparse or dense.

First we need a function that can toggle sparse argument. for a given step, the function should set all sparse arguments that are set to "auto" and respects if they are already set to "yes" or "no".

secondly, and harder, is a function that estimates the amount of sparsity that is produces from a recipe. For now it will be fairly simple since we don't have input-output information. It should further rely on early exits for maximal performance. e.i. if the recipe doesn't contain sparse steps -> early return.
