4a78a24034 Copy all byte slices from decoder 
While trying to optimize things I overread this: "the byte slices returned by the Decoder methods are only valid until the next call to any other Decode method."

5d89d87a2d Reduce gaps/rewrites in the same cell with offset 
A new buffer remembers the timestamp of the first write.
Instead of cutting of cells relative to that time, have
a little "time buffer" so that rewriting the same cell twice
happens less often.

becf41f98c Reset buffer size when reused 
The buffers data slice size needs to be reset to 0
before it can be reused. Also, buffers that come from
the archive should not be reused as they might have
strange capacities.
