enricher_internal.R code may have mistake

[tangmaomao16]

At the 100th line code in https://github.com/YuLab-SMU/DOSE/blob/master/R/enricher_internal.R, it is numWdrawn=k-1, it should represent the number of the real terms we get, but why minus one? I think 'minus one' is wrong. The right code should be numWdrawn=k
