wasm2luau option to disable use of Roblox library

[dphfox]

wasm2luau seems to rely on Vector3.new from the Roblox standard library (presumably to take advantage of vector optimisations). This prevents its use in standalone runtimes like Lune which don't provide these library members.

There was a Rust build option that you could use to have Wasynth generate code with a Luau-based Vector3 implementation. I'm pretty sure it still exists.

Alternatively you can use https://github.com/RealEthanPlayzDev/LuauCeption/blob/main/snippets/VanillaV3.luau (from my project, LuauCeption)

The feature flag in question is vector, which is enabled by default. You have to build from inside the codegen/luau directory for --no-default-features to work properly (see rust-lang/cargo#8366). Also, as of #35, the generated code will check for vector, which lune implements (although I haven't tested this myself).
