This is a major release focusing on performance optimisation of the geometric correction. It includes a significant internal refactor to the orbit and geocoding modules.
- added an implementation of the Newton-Raphson method to find the zero Doppler azimuth times. It is now the default method
- added the option to seed the initial azimuth time guess with a run on a subsampled DEM. It halves beckward geocoding computation time in most cases
- support Python 3.10+ and modernise code
