stages: separate scanning and parsing, allowing `v`, `vn`, `vt` lines to be mapped to line numbers and store line data (once). first stage parsing: parse face data and validate vertices. TODO: * improve validation (detect partial normals/texcoords); * maybe improve storage of triangle line number instead of storing line number for each vertex;
