On Mac, `camera_calibration_parsers_wrapper` cannot be imported in python

[rmaronson]

The library camera_calibration_parser_wrapper on Mac is built as camera_calibration_parsers_wrapper.dylib, but python only imports packages with the extension .so.

I believe this can be fixed by setting the suffix explicitly, by e.g.

set_target_properties(${package_name}_wrapper PROPERTIES SUFFIX ".so")

Compare line 97 in the CMakeLists file for tf2_py, https://github.com/ros/geometry2/blob/melodic-devel/tf2_py/CMakeLists.txt. Will test and attach a PR if it works.
