Handling of additional files besides the main input file

[andreaskern74]

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

Currently the framework architecture assumes that there is exactly one input file which will be checked. The checker bundles may look into referenced files, but the is no guarantee that these files are accessible in all stages of the process.

Example: When checking an OpenSCENARIO XML file, then it might be useful to also process the referenced OpenDRIVE file.

Describe the solution you'd like

Not clear at the moment. Topics to consider:

• Do the user need to add the information to the configuration or is there an automatic step done by the implementation of the checker bundles?
• Possibility to report issue locations in the referenced file?

Additional context

See #113

Here is the status of the current implementation.

• The qc-openscenarioxml checker bundle handles the referenced OpenDRIVE file in the OpenScenario XML file, using this function. We can do that as each OpenScenario XML file contains the path to the referenced OpenDrive file.
• The result file format currently does not support reporting locations in the reference files.
