Utility to process Doom IWAD files for Doom8088, Doom8088: Motorola 68000 Edition, doomtd3 and ELKSDOOM.

It writes a new WAD file.

This is required to reduce the memory footprint of some of the data structures in Doom to get it to fit in 64 kB.

We will pre-calculate more fields so that the lumps stored in the WAD can be used directly from the WAD rather than having to load and convert them in memory.

For example:

By storing vertexes in LINEDEFS and SEGS the VERTEXES lump can be removed.

Build: mvn verify
