Bug in w2rho() loop body / croco_pytools v2.0.4

Hi all,
While working with croco_pytools v2.0.4, I found a bug in the w2rho() function (prepro/Modules/Cgrid_transformation_tools.py).
Loop body, incorrect slice

Current(wrong): var_w[iz + 2 :, :]
Fix: var_w[iz + 2, :, :]

The open slice returns a 3D sub-array instead of a 2D layer, breaking the interpolation arithmetic for all interior levels.
Best,
Bruno H.
