Implemented bin deflation based on the relative DOS value. If it is
lower than numerical precision, it is set to zero and the bin is marked
as not contributing. Optimized configuration search by seting extrema
configurations to those found in the extrema search.
isolated an issue with deflation where small extrema bin ranges would
appear extremely flat simply due to sparsity. Can not directly limit
flatness calculations to require a set number of bins, else these
intervals would never converge when under calculation.
