Merge pull request #399 from Aceeri/colliderview-conversions

Conversions from `ColliderView` into parry's `SharedShape`/`TypedShape`

CHANGELOG.md

 ## Unreleased
 ### Added
+- `ColliderView::as_typed_shape` and `::to_shared_shape` to convert a `ColliderView` to a parry’s
+    `TypedShape` or `SharedShape`. The `From` trait has also been implemented accordingly.
+- Implement `Copy` for `ColliderView` and all the other non-mut shape views.
 - Add `RapierContext::rigid_body_colliders` to retrieve all collider entities attached to this rigid-body.
