* Make WAL replay benchmark more representative

* Move decoding records from the WAL into goroutine
Decoding the WAL records accounts for a significant amount of time on
startup, and can be done in parallel with creating series/samples to
speed up startup. However, records still must be handled in order, so
only a single goroutine can do the decoding.
