Added triangle stripification functionality and updated MD5 mesh conversion process.
Added functions for parsing face vertices and stripifying triangles and quads. Updated the main conversion logic to support vertex color and strip generation options.

These enhancements will support strip geometry by strip generation options for both obj2dl and md5_to_dsma.
Why this can be useful and significant feature ?
Nintendo DS has limited GPU vertices limit (6144) and every vertex economy is a big deal.
Strip can reduce the vertices count avoiding duplicate vertices.
The reduction can be ~30% vertices.
For example in retail game, Dementium II that have impressive 3D graphics and render on DS use a lot stripping allow to economize vertices count to ensure to respect both 60fps performance and 6144 vertices limits with immersive atmosphere.
How to enable/use this ?
This is enabled by default on obj2dl and md5_to_dsma.
To disable stripping and return to classic geometry the flags "--no-strip" can do this.
This feature was tested?
Yes, I tested this feature with teapot and robot assets example from the library and it work totally fine the geometry and UV is preserved no weirdness and teapot look more good that the original.
Of course further test can be made but this seem to be functional.
