Adding a note, mostly for myself, to address later.
The approach here works but it is sub-optimal. Suppose I have this DataFrame:
```
+--------------+--------------+
| a | b |
+--------------+--------------+
| 0.1111111111 | [1, 2, 3] |
| 0.2222222222 | |
| | [4, 5, 6, 7] |
| 0.4444444444 | [] |
+--------------+--------------+
```
Now I want to make a simple transformation. I want to check if the values
are equal to the literal `1`.
It would be nice to have something along the lines of
```rust
df.select(vec![array_transform(col("b").eq(lit(1))])
```
