Improved C++ base library

[andreaskern74]

Is your feature request related to a problem? Please describe.

The C++ base library has a long history and is part of the framework, because from ASAM it is currently only used for framework components. During the first development iteration with the checker libraries for ASAM OpenDRIVE, OpenSCENARIO XML and OTX (all v1.0.0), a Python Base Library was introduced. This library has much more functionality and is easier to use. The C++ base library was just maintained to preserve compatibility.

If somebody wants to create an own C++ checker library, then he has a dependency to the whole framework, including transitive ones like Qt, which is actually not necessary for this use case.

Describe the solution you'd like

An improved C++ base library

• as few dependencies as possible
• using modern C++ code
• architecture and functionality preferably aligned with the Python version

Additional context

If this should be provided

• as an own repository (like the Python version) or still as part of the framework
• as compiled library or just as code to include in own projects

can be discussed/decided later.

Note

With work like in #191 we are getting less C++ code in the framework, but it is still needed for the result GUI and the 3D viewer plugin!

When this feature is provided, then an additional user is necessary who is implementing an own checker library based on this new library to validate the new architecture. Without, this is just a needless academic work.
