> we can probably avoid an additional allocation for sliced arrays by making
a version of `slice()` that consumes self -- like `sliced()` perhaps 🤔
_Originally posted by @alamb in

The idea is that calling `ArrayData::slice()` creates a *new* array data
(needs to allocate a Vec for the new child buffers). For some cases, the caller
owns the ArrayData and thus could simply reuse the allocation by taking it as
owned
Something like
```rust
impl ArrayData {
/// Like Self::sliced, but takes an owned self, and reuses the
allocations, making it more efficient
fn sliced(self, offset: usize, len: usize) -> Self {
...
}
}
```
