Utility for taking the value from a cell of a option without cloning.
Add `take-cell-option = "0.1"` to your dependencies.
```rust
use take_cell_option::take;
use core::cell::Cell;
let cell = Cell::new(Some(Box::new(10)));
let v = take(&cell);
assert_eq!(*v.unwrap(), 10);
assert!(cell.into_inner().is_none());
```
