Implemented an Inverse Distance Weighted interpolation function in GeoElevationFile. Also added a wrapper in GeoElevationData called _IDW. Both functions are marked private currently so they are not directly added to the public API. I think InverseDistanceWeight in the GeoElevationFile could just be made public, but the _IDW function in GeoElevationData should probably be merged into get_elevation().
Both functions have docstrings and robust unittests. The unittests make use of a local tile instead of relying on the network for algorithm testing. The tests check the boundaries of the tiles to verify there are no errors.

Basic usage:
elevation = myGeoElevationFile._InverseDistanceWeighted(latitude, longitude)orelevation = myGeoElevationData._IDW(latitude, longitude)
