0.12.39

Added

• We now instrument temp space, time, and memory used building two k=27 on ci for performance tracking and comparison one for each back propagation method.

Changed

• We added a -e flag to allow you to choose between bitfield back propagation and the original back propagation. This brings performance a little ahead of the Beta 17 plotter release. However bitfield back propagation may perform faster on spinning disk. YMMV.
• More of the sorts in the bitfield sort use uniform sort for better performance.
• This version requires slightly more RAM at each k size.

Fixed

• Previous releases were not deleting temp files as they were no longer needed and therefor temp space needed for a k=32 went from 332 GiB to 499 GiB. This version only needs 332 GiB when using -u 64.
• Beta 17 style back prop had a buck that could occasionally lead to a segfault. We fixed that when using the -e flag.
