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.

Fabian Reinartz 8c48dc2ca5 chunks: varint encoding in first full 64bit numbers 
This saves about 7 bytes per chunk

Fabian Reinartz 5e76fd3126 chunks: drop shift, remove branch 
This removes the need for the shift value and just calculates
everything on the fly through count.
Removes a branch condition.

Fabian Reinartz c9ee572709 chunks: don't mutate in bstream iterator 
This replaces mutation of underlying bytes in the iterated slice
with a shift counter, which is used when reading the head byte.
This is avoids having to copy the entire slice for every new iterator.

Fabian Reinartz fa181a34c1 chunks: cleanup anything but xor encoding 
xor encoding is fast enough for our purposes and provides
very good compression.
We remove all other ones that partially don't support floats
for the sake of simplicity.
