Make experiments list where virtual view moves on a parametric curve.
vsrs/list_parametric_experiments parameters.json x_key y_key frames out_experiments.json
Dataset must be 2D. Curve is defined inside script, as with misc/extract_parametric.
Input views are on a regular index grid, with x_key and y_key intervals.
For each virtual view, the closest leftside and rightside input views are used. (not perfect)
