Erik Dubbelboer a01a7b12c9 Reuse buffers and objects using sync.Pool 
This reduces the amount of garbage generated and relieves pressure on
the GC.

For a workload without reusing the Writer (using Writer.Reset) the number of allocations goes from 31 to 9.
While for a workload when you reuse the Writer the number of allocations goes from 25 to 0.
