Add functions for adding library during interactive development

New `clojure.repl.deps` namespace which is automatically referred into `basilisp.user` and which includes the following functions:

```
add-lib
add-libs
sync-deps
```

Probably will rely on some sort of other tooling for downloading dependencies which does not exist right now.
