Update to sqlite-client to support error handling

[etiennenoel]

@michaelpeterlee I've moved the sqlite-client to this repo that I'm maintaining and I've removed the comlink dependency. If you have a moment at some point to try it out, that would be great. We can also add features that you were talking about such as supporting transaction.

I've tested this library in this repo (and it works): https://github.com/magieno/sqlite-client-demo

Thanks @etiennenoel, I think it's good for the community to supply a SQLite/WebSQL compatible WASM client. The transaction() signature as per SQLite/WebSQL is great.

I'm currently distracted with other projects, but have earmarked this for review a little later.
