Review Comment:
It seems wasteful to create a Python list for this, but I'm having trouble
finding a better solution. It looks like we can create an array of nulls and
replace null with True, like this:
```python
null_arr = pa.nulls(10, type=pa.bool_())
true_arr = pa.fill_null(True)
```
Unfortunately, I don't see an easy way to set individual values to False in
the resulting array.
