Title: Add some TrustWorthy pragmas.

The following modules should be safe:

Control.Lens.Action
Control.Lens.Level
- use Data.Profunctor.Unsafe (safely)

Control.Lens.Each
Control.Lens.Empty
- use Data.Profunctor.Unsafe (safely)
- dependencies with insufficient SafeHaskell support: vector, unordered-containers

Control.Lens.Internal.ByteString
- implemented in terms of ByteString internals
