Implement viewport voxel value display

Option to display individual voxel values numerically in the viewport.

Implement max value display for vector grids

Implement max value display for scalar grids

Simplify openvdb freeing

Implement RNA to get absolute OpenVDB path

This is to simplify getting the path in Cycles.

Remove useless rna include and clean indentation

Remove unnecessary inspection functions

Remove unnecessary default option

Implement decimation for vector grids

Fix compilation without OpenVDB or Smoke modifier

Stop simplify and hide properties from affecting render

Make some VDB props non-animatable

Implement split color channel assignment

This allows the color channel to have individual grids assigned, when
vector grids were exported as separate float grids.

Low res display option (decimation) and indexing fixes

This implements a new feature for faster display by reducing the
resolution of the displayed cache.

This also fixes some mistakes with cache indexing and coords.

Fix updating when changing selection with 'hide unselected'

Fix cache not updating on frame index 0

Fix coords with axis inversion

Fix jitter with axis inversion

Improve safety of the vdb pointer in sds

Fix cache not updating when chaning properties
