The ZBSPTREE.WAD doesn't contain "Data for binary space partitioning trees" as the disasm_guide.txt suggests but instead is random garbage data designed to
- push the actual game data to the outer region of the CD which spins and reads faster
- make the game harder to download with internet speeds of 1996
and thus can be safely ignored/removed. Also it seems that point 1 was never realized as intended since the file ordering on the mastered disk is as such that the game data actually is written first (to the inner ring) and the garbage to the outer ring.
