[lib] Add full feature for lib

Problem: `lib` crate is intended to be shared across
all other crates, thou some deps and trait impls make sense
only for specific use cases. For example, websocket client crate
wouldn't ever need sqlx trait impls.

Solution: Add `full` feature to be able to opt out unnecessary
deps if they are not needed.
