fix: render *

Browse source 
fix:
- fix texture for each direction (north texture is in north etc)
- fix mirror textures (the left of each texture is at its left)
- fix dimensions (walls are 1x1 for any window dimensions or FOV)
- optimize render()

dev:
- add testmaps/good_directions_test.cub
- add textures/test/*.xpm
