MIKE 21 & MIKE 3 hotfix 01-12-2021

This hotfix resolves a number of issues:

• possible memory issue when using the Shoreline Module in a domain that is resolved by many elements
• error in the Spectral Wave module related to reflection from structures in combination with the use of “Directional sector” for the directional discretization
• error in the Spectral Wave module in case of wave blocking using current in combination with quasi-stationary formulation for the fully spectral formulation
• error in the Mud Transport module related to use of hindered settling
