Update to the hake Reference Case model incorporating the 2020 commercial and 2021 survey data

The Reference Case Ricker hake assessment model is updated with 2020 commercial and 2021 survey data. The updated assessment results are compatible with the previous (2020) Reference Case results and suggest a continued steady increase in spawning biomass for M. capensis but a recent decrease for M. paradoxus, with these estimates for both species lying well above BMSY.
