Commit Message

Serialization Overhaul (#81)

* overhaul serizalition code

* unify access to Input(De)Serializers behind facades to leverage the default methods for various input/output channels
* drop implicit buffering/decompressing as this should be decided where the stream are constructed (user-land)
* remove/cleanup the (now) unused code

* taf cleanups

* fix wording
