shareloc.geomodels.rpc_readers.rpc_reader(geomodel_path, topleftconvention=True)

Load from any RPC (auto identify driver) from filename (dimap, ossim kwl, geotiff)

TODO: topleftconvention always to True, set a standard and remove the option

topleftconvention boolean: [0,0] position

If False : [0,0] is at the center of the Top Left pixel If True : [0,0] is at the top left of the Top Left pixel (OSSIM)
