Add Horizontal Offset support to Holograms

[test137E29B]

Description

Hologram projectors are really nice things to use, but they lack horizontal offset support meaning any design without a central block annoyingly has an offset hologram. This PR adds support for them to be up to 32 blocks away horizontally. This offers more options to hide the projector in the wall or ceiling, while also allowing them to be centered nicely along any axis.

Proposed changes

• Add X offset to hologram projectors
• Add Z offset to hologram projectors
• Clean up code a little with the new additions
