Update normalized persistent entropy definition #83

Closed maxchumley closed 10 months ago

Current method is inconsistent with literature. Dividing by the log of the sum of the lifetimes can make the normalized entropy negative for some point clouds. It is now computed by dividing by the log of the number of intervals.
