gtfs realtime proof of concept

this adds a package for protobuf stuff, generated via hprotoc. Seems to
work kinda fine?

(the generated API is horrible though, will have to write some wrappers
for that)

+## Packages & Modules
+
+This project is split into a few haskell packages:
+ - the tracktrain executable in `app/`, handling startup & config
+ - the tracktrain library implementing the business logic in `lib/`
+ - the gtfs realtime library (generated with `hprotoc` from the gtfs realtime 
+   proto file, along with a very little glue code in `Servant.GTFS.Realtime`)
+   in `gtfs/`
+ - that's it for now, but there'll probably be more
