[feature] Implement my BSP parser

[Derpius]

Describe the solution you'd like Replace the existing call to traceline with my BSP parser

Additional context As it currently stands, the parser only works correctly when compiled with GCC Compiling with MSVC (which is needed for source ABI compatibility) causes normal mapping to break

[Derpius]

Almost done, just need to swap loading texdata paths as textures to materials (why are they called texdatas), and fix normals etc

[Derpius]

Normals and materials fixed, however displacements still have severe artefacts

[Derpius]

Also need to add a hitworld bool to accel building and rebuilding

[Derpius]

Displacement normals fixed, still need to add hitworld bool and transform tangents and binormals along with normals

[Derpius]

TBN finished but now i have another issue of crashing on loading a more complex map like something from TF2

[Derpius]

Fixed, issue was with my FreeAll function not setting pointers to null
Only thing left to do is add a hit world parameter back into the build function

[Derpius]

Displacement texture blending added
