ZInflate (z_inflate_new) holds the bit reader, the RFC tables and every table and scratch list a block
builds, rebuilt in place: an inflate allocates nothing, and a worker thread inflates in a context of its
own (made on the program's thread). z_inflate_in / z_uncompress_in / z_gunzip_in take it; z_inflate /
z_uncompress / z_gunzip and every caller (image, atlas, tiled, render3d's png_decode) are unchanged and
work in RtInflateState's one context. The old per-call lit/dist tables were also leaked on an error
return; there are none now. Compiles: Maroon Lake headless, examples/library/tiled_p2 and tiled_p6.
