Rename bitswap (#25) 

* use PeerInfo in event handlers

* use CidV1 and raw multicodec as default

* add block stream abstraction

* raises defect

* adding dataset abstraction

* move blockstream into own dir

* reorg files and fix tests

* rename dataset to blockset

* wip

* wip

* adding basic test for treehash algo

* run blockset tests along with with the rest

* remove obsolete contents

* fix chunker tests

* rename bitswap and move to stores

* rename bitwsap to blockexc and move to stores

* moare project structure reorg
