May not require any wrapping, if so then this ticket is just for tracking. Otherwise, adjust SP.
Wrap meas_base with pybind11
Wrap pipe_base with pybind11
Wrap obs_base (was daf_butlerUtils) with pybind11
Has a non-trivial dependency on `cameraGeom`, and possibly other code. For now I'll assume this can be fixed as part of DM-8423.
Package does contain some C++ code, as well as various swigisms.
Looks fine. Minor issues on PR.
Merged with all requested changes.
