Remove multiple heads
...
This changes the structure to a single WAL backed by a single head
block.
Parts of the head block can be compacted. This relieves us from any head
amangement and greatly simplifies any consistency and isolation concerns
by just having a single head.

When checking for amended points, do it in terms of bits.
...
NaN != NaN, so the previous code would incorrectly report
it as changed.
There's also plans to take advantage of the NaN payload,
so look at the entire value.

Drop position mapper from head block
...
The position mapper was intended to pre-computed "expensive" ordering
of label sets. It was expensive to update and caused a lot of trouble.
Skipping this optimization entirely actually revelead it was pointless
and even harmful from the e2e perspective.

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.
