taum not updated in sbcice_cice

Description
In sbcice_cice utau and vtau are updated to be a combination of the wind stress and ocean-ice stress. taum is not updated and is used later in the TKE or GLS scheme. This means that under sea-ice the surface stress input to the TKE/GLS schemes is probably too large.

I plan to fix this by adding the following extra lines to sbcice_cice.F90 at line 566 (in subroutine cice_sbc_out)
! Also need ice/ocean stress on T points so that taum can be updated ! This interpolation is already done in CICE so best to use those values CALL cice2nemo(strocnxT,ztmp1,'T',-1.) CALL cice2nemo(strocnyT,ztmp2,'T',-1.) ! Update taum with modulus of ice-ocean stress taum(:,:)=(1.0-fr_i(:,:))*taum(:,:)+SQRT(ztmp1^2. + ztmp2^2.)strocnxT and strocnyT are already calculated (by interpolation) in CICE so I don't think there is any point interpolating them again in NEMO.
