Spectral: legacy planks add-on

An add-on for the Spectral resource pack that restores the old plank colors for two wood types - crimson and jungle.

With the release of Minecraft 1.20, two new wood types were added to the game, whose textures turned out to be too similar to the crimson and jungle planks from Spectral. As a result, the pack authors changed their design, but this add-on allows you to preserve the previous style - the pink and yellow planks that were in the original Spectral.
