Add block bounding box data

[IceTank]

The current block shapes data only represents a blocks collision box but not a blocks bounding box as seen when hovering over a block.

The current name used in mineflayer is also misleading as it implies that you can select blocks with something like a raycast operator by there bounding box. This does however not work as blocks like wheat that are treated like empty blocks because they have no collision and therefor no shape data.
