In Tutorials/HIT/prob_init.cpp, Lz was computed as probhi[2]-problo[1], a copy-paste of the Ly line. When problo[1] != problo[2] the initial cos(2*pi*z/Lz) velocity field is not periodic in z, giving a discontinuity across the periodic z boundary at step 0, and disagrees with the forcing, which uses probhi[2]-problo[2] in TurbulentForcing::init_turbulent_forcing and explicitly permits Lz > Lx. No behavior change for the shipped inputs, which all use symmetric prob_lo. Fixes AMReX-Fluids#180
