Fabian Reinartz 9790aa98ac Add postings wrapper that emits head postings in label set order 
This adds a position mapper that takes series from a head block
in the order they were appended and creates a mapping representing
them in order of their label sets.

Write-repair of the postings list would cause very expensive writing.
Hence, we keep them as they are and only apply the postition mapping
at the very end, after a postings list has been sufficienctly reduced
through intersections etc.

Fabian Reinartz beb842a856 Change block interface 
This changes the block interface to directly expose index
and series readers rather than the direct querier

Fabian Reinartz 5d75a3dc7b Add basic compaction 
This adds a basic compactor that will merge two persisted blocks into
one. It simply fully rewrites the index and concatenates the chunk
lists.

It just writes into the current working dir and doesn't properly handle
which blocks to compact for now.
