ReLU with a small slope on the negative side.

$$
\mathrm{leaky\_relu}(x) = \begin{cases} x & x > 0 \\ \mathrm{negative\_slope}\cdot x & x \le 0 \end{cases}
$$

**Parameters**

- `input`: the input tensor.
- `negative_slope`: the negative-side slope. Default `0.01`.

**Throws**

- `ClikaRT::Error`: when the input's dtype is not served for this operation (the machine-readable reason rides `code_name()`).

**Returns:** a new tensor, same shape and dtype as `input`.

```cpp
auto y = ClikaRT::ops::leaky_relu(x, 0.2);
```
