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.

Fabian Reinartz af36c89178 Make adapter work + comment it out 
The adapter drags in a whole dependency chain of Prometheus internal
packages due to its storage's hideous structure.
With dependency flattening the adapter can actually be included into
Prometheus in a working way but it breaks package builds. Thus we
comment it out until we found a way to fix this contraption.
