rust crate libwfa

[hangsuUNC]

Hi,

I was trying to use libwfa for a rust code, but failed to compile. The error message suggests stderr value is not found in the scope of the file affine_wavefront.rs (affine_wavefront.rs at line 187. The compiler suggests importing stderr from std::io::stderr). Is this an easy fix or is this crate totally out of maintenance?

Best,

Hang
