Title: v1.1.28 Added rarefy_even_depth

Added new function to transform abundance tables (otuTable) to even
sampling depth (number of reads per sample). This is sometimes
(somewhat mistakenly) called "rarefaction", though it actually a single
random subsampling procedure in this case. The original rarefaction
procedure includes many random subsampling iterations at increasing
depth as a means to infer richness/alpha-diversity
