piv_replace_outliers — PIV `validate` op

• Data kinds: flow2d × mask → flow2d

• Call: import fullseye as fs; fs.ledger.piv_replace_outliers(flow, mask, method='median') (to call the implementation directly, import pivops; pivops.piv_replace_outliers(flow, mask, method='median'); from the registry, opspiv.get("piv_replace_outliers"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

外れ値を近傍で埋める。`method="nan"` なら埋めずに欠測にする。

埋めた場所と実測を区別できなくなるのが埋め込みの代償なので、

どこを埋めたかは呼ぶ側が `mask` として持っている前提にしてある

(この op は mask を返さない —— 入力として受け取ったものだから)。
