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

change NodeCache protection to STM
...
- putting the NodeCache behind an IORef had been chose because those
could've been read non-blocking
- the same is true for TVars. The performance characteristics are likely
worse, but at the advantage of composability within STM monads

protect concurrent node state access with STM
...
- for allowing concurrent access to predecessors and successors, the
whole LocalNodeState is passed wrapped into an STM TVar
- this allows keeping the tests for the mostly pure data type, compared
to protecting only the successor and predecessor list

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
