CICE6.4.2 updates CICE6.4.1 from December, 2022 and includes Icepack1.3.4.

This release has several minor bug fixes including to computation of thin ice/snow enthalpy snow physics, FSD lateral melt, and the VP solver. It corrects some errors in halo and global sum infrastructure and extends unit testing of both features. It adds an option for use of JRA55do forcing and deprecates the COREII LYq forcing. Several history and restart output features were added including the ability to have multiple restart frequencies and to set history averaging separately for each history stream.
