Switch to 16-bit truecolor framebuffer and PNG assets

pbio moves to git.bnd.wtf/irrlicht/pbio.git branch truecolor16: the
framebuffer is now RGB565 u16, no palette. Assets are loaded from PNG via
the png crate and quantized to RGB565 on load; transparency comes from the
alpha channel as a per-tile opacity mask, so any color (black included) can
be opaque. The TGA loader and the palette-order fragility are gone.

overworld.png is the unmodified Mini-Medieval Overworld sheet (same 24-column
layout as the old TGA, so map tile ids are unchanged); entities.png holds the
player sprite extracted from the old entities.tga.

Adds an ignored snapshot test that renders the first frame headlessly to a
PNG for eyeballing the renderer without a window.
