Parse the pixel status mask in the data stream

The pixel status mask (Section A.5 Pixel-wise Status Info in the R1 data model, A.1.5 Pixel-wise Status Info in the DL0 data model) must be parsed:

• in preparation of the update to handle DL0 data with DVR enabled. The "DVR info" must be retrieved
• in preparation of applying the "dynamic" (per-pixel per-event) PixelTimeShift calibration, once the CR to the R1 data model is implemented. The "channel info" must be retrieved so the pixi time shift of the selected gain can be applied.

The mask is defined as:
