Not compatible with onnxruntime-web >= 1.19.0

[pocka]

This package uses¹ a versioned WASM binary file of ONNX runtime Web fetched from CDN².
Due to the WASM file is for onnxruntime-web@1.18.0 and onnxruntime-web@1.19.0 seems not to be compatible with that WASM file, using this library with onnxruntime-web@1.19.0 (and probably later versions) throws an exception at predict().

# Firefox (no stack trace...)

Adding an escape-hatch like #7 would solve this problem.
Or, narrowing peerDependencies.onnxruntime-web to 1.18.x would reduce the chance of users installing >= 1.19.0.
As a workaround, users can avoid the error by pinning onnxruntime-web to 1.18.0 in project's package.json.
