Introduce trilinear flex parametrization.
...
These flexes use only 24 DOFs (3 per vertex of the bounding box), while colliding with the full high resolution mesh.
On an 8x8x8 cube, the performance using DOFs at all vertices is
```
Simulation time : 18.74 s
Steps per second : 533
Realtime factor : 0.53 x
Time per step : 1874.4 µs
Contacts per step : 114.88
Constraints per step : 3322.51
Degrees of freedom : 1536
```
With the new implementation, it is the following:
```
Simulation time : 1.82 s
Steps per second : 5507
Realtime factor : 5.51 x
Time per step : 181.6 µs
Contacts per step : 38.84

Change site and frame attach API.
...
Old API:
```
site.attach(child_spec)
frame.attach(child_spec)
```
New API:
```
parent_spec.attach(child_spec, frame=frame_name_or_object)
parent_spec.attach(site_spec, site=site_name_or_object)
```
This enables accessing the parent object during attach, which will be used in a follow-up CL to automatically append the child assets to the parent.
