Max pooling to a fixed 3-D output size, the window derived per output position; the input is channels-last. The module form of [`ClikaRT::ops::adaptive_max_pool3d`](../ops/adaptive_max_pool3d.md#adaptive_max_pool3d), which documents the full contract (shapes, dtypes, errors); construct once, then call it like a function.
