Andy Balholm 94609f9606 Revert "Faster bit writing." 
This reverts commit c3da72aa01.

With the sample data from issue 22, one byte in the output file is zero
instead of the correct value. For now at least, we'll go back to the old
way of writing bits.

Fixes #22

Andy Balholm c3da72aa01 Faster bit writing. 
Replace the functions in write_bits.go with a bitWriter type based on
the compress/flate package.

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.

It doesn't really have the performance benefit I thought it did.
