HazImp v1.3

What's Changed

Add storm surge job templates and remove some deprecated wind templates. The surge template calculates water depth above floor height based on the difference between floor height above ground and water depth above ground, where the floor height is an attribute of each exposure element (the existing flood templates assume a fixed floor height above ground for all exposure elements). Example case included.
