Bump version to v0.1.6 (#8744)

## Summary

Implements
[FURB152](https://github.com/dosisod/refurb/blob/master/docs/checks.md#furb152-use-math-constant)
that checks for literals that are similar to constants in `math` module,
for example:

```python
A = 3.141592 * r ** 2
```

Use instead:
```python
A = math.pi * r ** 2
```

Related to #1348.
