keypoint op• Data kinds: points → keypoints
• Call: import reprconv; reprconv.points_zyx_to_keypoints_uv(points) (or opsreprconv.get("points_zyx_to_keypoints_uv"))
A point set `(N,3) = (z, y, x) → image coordinates (N,2) = (u, v)`.

:func:keypoints_uv_to_points の逆向き。不可逆 —— z が落ちる。
落ちる量は測れる: 往復して戻ってこない値は z 列そのもので、
`selftest` は「z の RMS = 落とした情報量」として数字で出す。
Args:
points: (N, 3) の (z, y, x)。
Returns:
(N, 2) float64 の (u, v) = (x, y)。
Raises:
ValueError: 形状不正 / 非有限。
