2a5433b has added support for BSPX¹²
I'd like to build out LumpClasses for every known lump type
At present I've only found Quake II Re-Release maps w/ BSPX data
https://github.com/ericwa/ericw-tools/ can generate some BSPX lumps, but not all³

A few lumps are deprecated / made redundant by other implementations

• FACENORMALS is an ericw replacement for VERTEXNORMALS
• DECOMPLED_LM replaces all LM* lumps

We aren't going to find 1 map with every lump type at once
Making maps with some BSPX lumps might require sourcing outdated versions of current compilers

If we do end up tracking down older tools, we should document & archive them
Could be helpful for dating older maps
