Optimize coordinate transformations in SARSensorModel

Cédric Traizet requested to merge optimize_sarmodel into develop

Summary

transformation between geographical coordinates and ECEF coordinates takes a lot of time in SarSensorModel computations. In the current implementation, a transform object is created for each transformation, this is very inefficient. Instead, the same transformation object can be created at class construction and used in each transformation.
