Rename FeatureData to e.g. SensorDetectionData

[PhRosenberger]

Describe the problem

After several years of discussion, I would finally propose to change FeatureData to something like SensorDetectionData to stop confusion with e.g. ISO23150.

Additional context

Relates to #367

@PhRosenberger, could you start a new branch for ISO23150 alignment?
And maybe a first pull request to solve this issue?
