lua use lcd_drawline to draw lines inside rliimages

rewrite draw_text to use new viewport buffer

set_viewport now accepts rliimage to allowe interfacing with rb. functions

fix long standing 2-bit bug with text drawing in lua
fix 2-bit img
saving bug (i'm guessing just a one off, just enabled clipping)

fix font_getstringsize bug

fix shape of numbers draw_num.lua also add auto centering
