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.

This is not useful for ClusterCockpit currently, but when archiving
a job or for the job-view, this can speed things up in the future.
