Slot map: array storage with persistent indices

Vec<T>-like collection with stable indices. The underlying array's indices are re-used by incrementing a versioning tag in the index type.

The SlotMapIndex type consists of a u32 for storing the index into the underlying array, and a u32 for storing the version. Deleting and inserting more times than the maximum value of u32 will cause overflow and index conflict bugs.

Example

```rust

use slotmapvec::*;

let mut map = SlotMapVec::new();

map.insert(123213); let idx = map.insert(34234); map.insert(654654);

map.remove(idx); let idx2 = map.insert(999); asserteq!(map.get(idx), None); asserteq!(map.get(idx2), Some(&999)); ```
