Add a calibrated tuning file for the OV2740 sensor based on the Intel
IPU6 AIQB shipped with the Lenovo ThinkPad X1 Carbon Gen 10, and the
Python parser that produced it. The first patch drops a now-dead guard
in SwStatsCpu::finishFrame() flagged during review of the v2 series.

Changes since v2:
- AIQB parser: tightened the file header docstring to avoid duplicating
  the argparse description, cited ia_cmc_types.h as the format source,
  removed the --black-level CLI flag (black levels belong in
  CameraSensorHelper, not in the tuning emitted by this script),
  introduced a ColorMatrixRecord dataclass so the id=18 unpacking
  reads as named fields, switched the YAML output to PyYAML via a
  Dumper subclass, and now write the YAML to <sensor>.yaml so the
  diagnostic prints don't have to be filtered out. (Laurent Pinchart)
- OV2740 tuning: no functional changes; regenerated against the
  updated parser to confirm the output is byte-identical.
- SwStatsCpu sumShift_ guard: no functional changes; rebased so it
  applies cleanly on top of the merged v5 AGC/AWB series.
