behold v0.1.0

First release.

Spin a 3D model in your terminal — one file, stdlib only.

• Loads .obj, .stl (binary + ASCII) and binary .fbx
• Character ramp by default; --blocks for truecolour half-blocks, --kitty for inline pixels
• Runs on the alternate screen, so it leaves your terminal exactly as it found it
• Bundles Spot (Keenan Crane, public domain) so it renders something out of the box
