Create Vue framework sdk

[aasoni]

1. Example for react sdk:
   https://github.com/clockworklabs/SpacetimeDB/tree/master/crates/bindings-typescript/src/react
   This should be the same but s/react/vue/

2. We should also have a Vue quickstart here: http://spacetimedb.com/docs/quickstarts/vue. See docs PR to see example of react quickstart: Misc docs and small CLI improvements #3953

3. We should also create a template here: https://github.com/clockworklabs/SpacetimeDB/tree/master/templates/vue-ts
