Compilation for `wasm32-unknown-emscripten` fails
Hello 👋,
I am trying to use tract in a project that compiles to the target wasm32-unknown-emscripten. This target seems not to be covered by the CI but I found a pull request that indicates compatibility.
When I try to compile tract, its tar dependency throws following error:

The people at tar seem to have a related pending pull request. Yet, I am not sure whether tar must be a required dependency for tract at all.
tar is required for the NNEF format, which I don't feel like putting behind conditional compilation as it is the primary format for tract.
Hopefully thetar crew crate will make it work soon, it does not sound like something that should be too hard, right?
The issue in tar seems to be fixed by now: https://github.com/alexcrichton/tar-rs/pull/397
