[PATCH v1 4/7] pipeline: rpi: Introduce CameraData::CropParams

Thu Aug 8 12:23:43 CEST 2024
In preparation for assigning separate crop windows for each stream, add
a new CropParams structure that stores the existing ispCrop_ and
ispMinCropSize_ as fields. Use a new std::map to store a CropParams
structure where the map key is the index of the stream configuration in
the CameraConfiguration vector.
At preset, only a single CropParams structure will be set at key == 0 to
preserve the existing crop handling logic.
