py::module_local() missing in bindings

[DaniGodin]

Hey,

Not really a bug but I think a "good practice" when exposing c++ bindings with pybind11.
Could you please mark the binded objects as py::module_local() to avoid symbol conflicts with other library.

Example:

py::class_<libCZI::IntRect>(m, "BBox") ---> py::class_<libCZI::IntRect>(m, "BBox", py::module_local())

Best,

Daniel
