A hook to obtain the result of the [`<Sampler />`](#sampler) as a buffer. Useful for driving anything other than `InstancedMesh` via the Sampler.

```js
const buffer = useSurfaceSampler(
  mesh, // Mesh to sample
  count, // [Optional] Number of samples (default: 16)
  transform, // [Optional] Transformation function. Same as in `<Sampler />`
  weight, // [Optional] Same as in `<Sampler />`
  instancedMesh // [Optional] Instanced mesh to scatter
)
```
