WASM bindings for ssi-sdk

It makes sense to keep the ssi implementations in ssi-sdk as much as possible, for mobile platforms, server and also web. The challenge is it being in golang.

WASM shows how this can be done.

Thanks to @moe for the inspiration here

we can build a wasm binary as part of the build:

The “work to be done” is identifying what apis and how to expose them to the Javascript runtime. Its similar to how the ssi-service exposes things over http, so we can use similar patterns I expect?

Any ideas of ssi-sdk functions that people want to try first directly from the browser?
