Embed the texture atlas data inside the exported .ps1bsp file and name those files after the actual map.
Makes it a bit easier to switch between maps for testing.

Reorganized texture code so that the palette is loaded separately, and metadata used to calculate UVs are kept out of the exported file for PS1.

Retired the concept of surface vertices, as UVs can in fact not be shared between polygons.
I may revisit this idea when trying to compress data size, as lighting data can be shared between poly vertices.

Overhaul of geometry conversion:
- Faces are now tessellated into one or more polygons, based on UV coordinates and texture tiling
- Polygons have their own vertex index list and light/UV values per vertex
- Lighting is sampled per polygon vertex, allowing for more light samples in general and more refined lighting
- There are still problems with reconstruction of vertices for sloped surfaces, but this is enough of a result for a checkpoint commit

Fixed some issues with texture atlas, page and ID generation. Texture references generally seem to be in order now, but UVs are still a problem.

Added computation of face area by projecting its vertices onto its plane and then generating a bounding box. Will be used for determining tessellation subdivisions.

First attempt at calculating lighting per face-vertex with smoothing based on the angle between faces, using edge adjacency to determine neighbouring faces.
Not quite right yet but it does get a result, and it's given me a good idea of what the correct solution for this should be.

Store sampled light data per face vertex, so we can individually light each face without having to average lighting values.
Keeping averaged light per vertex intact for now, as sampling isn't quite perfect yet and I like to have some options.

Write face vertex indices to output file instead of triangle data, which takes up less space and allows the PS1 code to decide how to draw the primitives.
