wasmgen continued - Githubissues

We're finally moving to webpack 4 on Yoroi and I need to update the wasm bindings to get it working.

I rebased the wallet-wasm2 onto master (since it's way out of date) and then tried to make the wasm generation work but there have been quite a few changes in the rust-cardano library since the wallet-wasm2 change so there's a bunch of compiler errors that need to be fixed.

I'd appreciate help fixing these if you have time 🙏
