v0.2.5

The highlight of this release is native Windows support (including JIT compilation). Everything should work out of the box; please open an issue if things are misbehaving.

There are a handful of API and feature changes as well:

• Removed threads parameter from various Settings objects when targeting wasm32, so that it's harder to accidentally spawn threads (which would panic).
• Removed min_depth / max_depth distinction in meshing; this doesn't actually guarantee manifold models (see this scale-invariant adversarial model), so the extra complexity isn't worth it.
• Added Windows support (including JIT)
• Removed write-xor-execute feature, which was extra cognitive load that no one had actually asked for; if you care about it, let me know!
