ocr-node example errors with unreachable code (possibly due to rten v0.11?)

[Robjam]

I cloned the project and after the following steps tried the ocr-node example and got the error:

❯ node index.js text-detection.rten text-recognition.rten ../../../ocrs/examples/rust-book.jpg
wasm://wasm/ocrs.wasm-0048fb06:1

Node.js v20.2.0

(slightly pedantic) Steps for reproduction:

1. git checkout main
2. cargo install wasm-bindgen-cli --version 0.2.89
3. cargo install wasm-opt
4. rustup target add wasm32-unknown-unknown
5. make wasm
6. cd ocrs/examples
7. sh ./download-models.sh
8. cp text-detection.rten ../../js/examples/ocr-node
9. cp text-recognition.rten ../../js/examples/ocr-node
10. node index.js text-detection.rten text-recognition.rten ../../../ocrs/examples/rust-book.jpg

I looked through the commit log and found that I can get a working wasm build with commit: 7e00182983b571fefd8302e10823dc4a09754140 git checkout 7e00182983b571fefd8302e10823dc4a09754140

Thanks for the report. This is indeed a bug in rten v0.11.0. I have updated the dependency to a patch release which resolves the issue. Please let me know if you still encounter issues running the example.
