Speed up stl format loading, especially with text format.

Browse Source 
Loading whole file now in memory (unless it's already a memory file).
And avoiding lots of memory allocations otherwise by buffering token string in class object.
Was a bit unusable before for large files (several minute loading times now down to a second)-

--------------------------
Changes in 1.9 (not yet released)
- stl meshloader now faster, especially with text format
- CMemoryReadFile::seek no longer allowed to go _before_ start.
- stl meshloader can now load 32 bit buffers.
Thanks @Foaly for the patch (https://irrlicht.sourceforge.io/forum/viewtopic.php?f=9&t=51441)
- Add IMeshBufffer::clone function to create buffer copies. CMeshManipulator::createMeshCopy uses that now and works now with all types of meshbuffers.
