This doesn't work in Python >=3.9 until Python 3.11. Multiple inheritance with `NamedTuple` has limited support. See: * python/cpython#19363 * python/cpython#88089 * python/cpython#92027

Adds a new function
isce3.geometry.get_bounding_radar_grid()that returns aRadarGridParametersobject that spans an inputGeoGridParametersobject. The output radar grid is the smallest radar grid that contains all points within the input geocoded grid over a user-specified height range. Additional margin may be added to extend the radar grid azimuth & range extents.This functionality is useful for implementing the static layers workflow. Many of the layers in the static layers product are computed from an input radar grid, but the input to the static layers workflow is a geo grid -- not a radar grid. Therefore we will need the ability to compute a radar grid that spans the input geo grid.
