WADS: New Freedoom wood crate textures

[SenhorFlibble]

Description of Changes

---

Last year I made a new set of TNT wood crate textures for Freedoom, uploading them here too instead of the older ones: CRATE4, CRWDH6, CRWDL12, CRWDS6

Hopefully I picked the prefix right.

I think the new ones are too diferent from the old ones, in terms of shading and also proportions like in crate4. Dont think its a good idea they outright replace the old ones.
