`isoCounts` for `seed=TRUE` is void

[bounlu]

Hi,

In the isoCounts function, when seed=TRUE is specified, it does nothing:

ids_counts_all = isoCounts(ids = isomirs, all = TRUE)
ids_counts_seed = isoCounts(ids = isomirs, seed = TRUE)

identical(counts(ids_counts_all), counts(ids_counts_seed))
[1] TRUE

Here is the code:
