Updating to avoid deprecated Producer/Consumer from `conduit`.
Removed unused imports.
Removing superfluous brackets.
Simplifying a few function bodies with catMaybe, fromMaybe, mapMaybe.
In particular this allows you to use `fromIntegral` without having to add the newtype wrapper. This can help existing code move away from importing and referencing the PortID type altogether.
Add flag imitating bson package PR for network changes.
Add stack files for compilation checking.
Both ghc86 builds work. Still need to fix ghc84 and under builds with older network code.
