Elementwise approximate equality, the elementwise map behind [`ops::allclose`](./allclose.md#allclose), same formula and defaults (`rtol` `1e-5`, `atol` `1e-8`, `equal_nan` `false`).

**Returns:** the broadcast-shaped `Bool` mask.

**Throws**

- `ClikaRT::Error`: (`INVALID_ARGUMENT`) when the operand shapes are not broadcast-compatible.
