Port TeleSculptor to Kwiver V2

[aronhelser]

Main changes are set/get_nested_algo_config, create_algorithm and some API changes to mesh_coloration

Sprokit has not been enabled in kwiver V2, so the single Sprokit dependent class is disabled.

Cuda has not been tested.

Superbuild configs not yet updated - external fletch and kwiver v2 were used so far, with updated default versions for dependencies from kwiver v2
