Enrichment score for stats

[jayhesselberth]

It would be nice if stat_activity_grouped provided some intuition on the magnitude and direction of the differences in the output.

For example, from #48:

#> # A tibble: 147 x 5
#>    activity     group   group1   p.value   q.value
#>    <chr>        <chr>   <chr>      <dbl>     <dbl>
#>  1 riboG_44     CD4/8 T NK+T   1.76e-172 2.59e-170
#>  2 Abasic_46    CD4/8 T NK+T   2.36e-137 1.73e-135

It's clear that CD4/8 and NK+T have very different riboG_44 activity—but which one has more?
