Trolli Schmittlauch 5e745cd035 only specify upper key bound when querying load 
As a querying node does not always know the lower bound of the queried
segment – determined by the predecessor – let the currently responsible
node provide that bound instead.

Trolli Schmittlauch f15d83baff Refactor predecessors and successors to hold RemoteNodeStates 
- neighbour nodes need to be contacted reliably
- Only holding NodeIDs requires a cache lookup for getting hostname and
  port. This is brittle as the entry could've been purged from cache.
- refactored ASN.1 scheme, types and add/ sort/ remove implementations

closes #46

Trolli Schmittlauch f8d444d5b6 FediChordMessage: last part has falg instead of parts number in each msg 
Motivation: Including the number of parts in each message part requires
the total number of parts to be known in advance, making dynamic
responses based on the received data difficult
