This error, actually, it's because the rusttype used by this library doesn't use the has-atomics feature.
But even after fixing this problem, it doesn't compile successfully on Rust version 1.78

rust version: rustc 1.77.1 (7cf61ebde 2024-03-27) rustup default :stable-x86_64-unknown-linux-gnu (default) wasmedge version 0.13.5 OS: ubuntu 22.04
After cloning the code from github, I run the command as follow:
cargo run --release --example image_classification -- ./assets/models/image_classification/efficientnet_lite0_fp32.tflite ./assets/testdata/img/burger.jpgthen I got such message, how to fix these errros?
