Cpp ovf reader writer
Created by: ax-meyer
New PR for this since the old one (https://github.com/Digital-Production-Aachen/OpenVectorFormatTools/pull/6) got quite messy beacuse it was based on a branch in a fork and stuff.
Copy form the old PR:
I've built a first proposal for a cpp reader / writer.
So far there is nothing async (although it is in some function names), everything is written dirty in header files, no parallelization so far.
It should be a base from which we can go forward
My c++ is not that great either, there are probably memory leaks somewhere.
The unittests will all run correctly because I don't have anything for c++ in the CI yet. Only the C# version is tested.
