build freenet-stdlib with no wasm

[gogo2464]

Hello. I am coding a pentest tool to exploit freenet sites when no authentication is required.

sadly currently I have:

#[cfg(all(not(target_family = "wasm"), feature = "use-node"))]
pub fn new() -> Result<Self, String> {
    unimplemented!()
}

So I can not build it :(

Could e implement it please?

issue closed.
