Process the cardiac ultrasound sequence in cardiac_sequence.nii.gz and complete the following:

4 evaluation criteria
A JSON file is produced containing the left ventricle contour coordinates for every frame in the sequence, with each frame's contour stored as a list of (x, y) coordinate pairs and keyed or indexed by frame number.
A PNG image is saved for each frame with the detected left ventricle contour drawn as an overlay on top of the original ultrasound frame, clearly delineating the ventricle boundary.
A single PNG plot is saved showing the left ventricle area (in pixels) on the y-axis versus frame index on the x-axis, with properly labeled axes, covering all frames in the sequence.
The area curve exhibits a plausible cyclic pattern consistent with cardiac contraction or relaxation across the frame sequence.
