chicory build.gradle.kts

The docs only showed how to do it in maven and it took a bit of trial and error before I got it working.

kapt is used rather than ksp despite being deprecated due to incompatibilities.

Also, example zig wasm

extern "wasm" fn log(ptr: [*]const u8, len: i32) void;

export fn add(a: i32, b: i32) i32 {
    log("Hello world!", 12);
    return a + b;
}

@HostModule("wasm")
class WasmHost(ctx: MyAppContext){
    @WasmExport
    fun log(memory: Memory, ptr: Int, len: Int) {
        val text = memory.readString(ptr, len)
        Log.i("WASM", "$text")
    }

    fun toHostFunctions(): Array<HostFunction> {
        return WasmHost_ModuleFactory.toHostFunctions(this)
    }
}

Note that you need to do extern "<module name>" which corresponds to @HostModule("<module name>"). Strings are passed as i32 pointers.
