Title: Use same GeoRaster instances for height and profile

Height and profile used to different instances of GeoRaster (representing the shapefile), which resulted in unneeded duplication of code and memory overhead.

This PR assures that the same GeoRaster is used for both services.

In addition, we now pre-load the COMB file on start of the application. This reduces the response time on the first call to height or profile considerably.
