ByteStreamCnvSvc+DataModelRunTests+SCT_RawDataByteStreamCnv: Byte stream metadata adjustments / fix tests.

Don't crash in ByteStreamEventStorageOutputSvc if there's no bytestream metadata. (Can happen for example if we're reading pool and writing bytestream.)

In RDP_ByteStream_jobOptions, add EventInfo as an additional dependency of StreamBS. (Needed for SCT_RawDataByteStreamCnv tests.)

ByteStreamTestWrite needs to define MetaDataStore. Also update its reference file, and extend the list of patterns to ignore in reference file comparison.

SCT_RawDataByteStreamCnv: Decoder test: Remove PixelModelData property from ClusterMakerTool. Encoder test: Turn off WriteEventlessFiles, to avoid crash during stop().
