Unbounded - represents a tracking space where the user is expected to move freely around their
environment, potentially even long distances from their starting point. Tracking in an unbounded
reference space is optimized for stability around the user's current position, and as such the
native origin may drift over time.

```ts
const XRSPACE_UNBOUNDED: "unbounded" = 'unbounded'
```
