Broken with latest syn version

As of today our build is breaking due to:

error[E0433]: failed to resolve: could not find `export` in `syn`
  --> /usr/local/cargo/registry/src/github.com-1ecc6299db9ec823/enum_dispatch-0.3.4/src/enum_dispatch_item.rs:56:11

    |                          ^^^^ not found in `syn::export`

It looks like this is due to the change here

Can probably be resolved by locking this dependency into the previous version?
