C++ Implementation possibility

I think the performance while using eCAL with foxglove would prove significantly better if the bridge was implemented in C++, similar to ecal-rerun-bridge.

Do you encounter specific problems with the bridge?
So far, I haven't seen any performance problems. We have recently fixed some internal memory leaks for the Python binding, which we will be releasing bugfix releases for (eCAL 5.13.3, eCAL 5.12.7).

When I initially implemented this bridge, I also tried implementing it in C++, but it was a lot more difficult to build, and I didn't see any benefits over the python version (latency, throughput, ...), so I dropped the C++ implementation.

I did notice the FPS drops with rerun while using python. Hence I believe while using high FPS topic visualisation, writing it in C++ would make it more resilient.

I am interested in contributing to the C++ implementation if there is any initiated. Python while having a GIL might cause bottlenecks when handling more topics at a higher FPS.
