Fornax

What Changed: * page the block atlas automatically instead of behind a flag * the flag was off by default, so a 512x pack just failed to load with "try a lower resolution resourcepack" and nothing pointing at the switch. * paging only ever runs when the alternative is that failure, so there was nothing for a setting to choose. * drop labPBR sidecars from every atlas, not just blocks. * entity and banner atlases were carrying 786 MB of maps nothing samples. * size the sprite-bounds grid to the pack. * a coarse grid forces a coarse placement pitch and wastes most of an overflow page. packs read it through fornax\_spriteGridCell now instead of hardcoding the number. * cap overflow pages by available memory rather than a fixed count, so a pack that will not fit refuses at load instead of swapping the machine. * log the sprite-bounds grid size when it rebuilds the grid is resized per pack now, and nothing said what it ended up at, so there was no way to tell whether a big pack's grid was released. **Full Changelog**: https://github.com/Icehunter/fornax/compare/v0.1.0…v0.2.0
