tsdb: use dennwc/varint to speed up WAL decoding (#9106)
* tsdb: use dennwc/varint to speed up decoding

This is a tiny library, MIT-licensed, which unrolls the loop to go
about twice as fast.

Needed to copy the sign-inverting logic inline, previously provided by
the `binary` package.

This directory contains the Prometheus storage layer that is used in its 2.x releases.

A writeup of its design can be found here.

Based on the Gorilla TSDB white papers.
