v0.7.1

• ReusableHyperOptimizer and DiskDict, allow splitting key into subdirectory structure for better performance. Enabled for new caches by default.
• High level interface functions accept the strip_exponent kwarg, which eagerly strips a scaling exponent (log10) as the contraction proceeds, avoiding issues to do with very large or very small numeric values.
