feat: Fully configurable layer envelopes (#1751)

This PR is to allow for fully configure the CuboidVolumeBuilder to define the envelope of the various layers. 
Allowing Navigation layers to be wider than just the size of the sensitive surfaces can help with problems seen in issue 
#1596 to account for the fact that the Navigator will extrapolate linearly from the last state, not taking into account that the track will bend. This is only relevant in telescope geometries.
