I am recently created a Python interface similar to the C++
camera_info_manager package used by many camera drivers. The API is
similar, but not identical. It supports the same calibration URL syntax
with variable substitution as by the C++ implementation.

There are probably not many camera drivers written in Python, but the
axis_camera driver needs camera info, so I chose to create a general
package to provide that interface for it.

My current implementation is unit-tested but not yet functionally complete.
It already has enough features to be useful. If you have or want to write a
camera driver in Python, please let me know. I will support this package
and provide any reasonable missing features it requires.
