I like it! One additional idea would be to change the layout of Boolean to
use a Bitmap instead of Buffer:
```
pub enum ArrayDataLayout {
Boolean { values: Bitmap },
...
```
If the Bitmap itself then stores a bit offset, we could remove the offset
from ArrayData. Slicing of Bitmap would then always be zero-copy and slicing an
array would push down the slicing into the validity buffer and layout.
This could in theory lead to a situation where you have different bit
offsets for validity and data in a BooleanArray. Probably not a problem for any
compute kernels, but could require copying in the FFI layer.
