Compute critical crack length
Description
This function implements Bettina Richter's (2019) parametrization for the critical crack length for flat simulations based on
density, grain size, and shear strength. The parametrization also needs the mean density of the slab, which can be computed
automatically if a snowprofile object is provided. In case the functions gets a snowprofileLayers object it expects slab_rho being precomputed.
This acts as a safety mechanism to ensure that slab_rho is computed over one profile and not over a stacked layers data.frame containing multiple
profiles. Note that the critical crack length can be computed alongside the layer probabilities for instability p_unstable in computePunstable.
