est_seq_error: Estimate sequencing error from counts.
In dcgerard/updogAlpha: Using Parental Data for Offspring Genotyping

Assuming that the reference allele is in great enough quantities so that there are enough points

1	est_seq_error(ncounts, ssize, ploidy = NULL, eps = NULL)

`ncounts`	A vector of non-negative integers. The ith element is the number of counts of the ith sample.
`ssize`	A vector of positive integers. The ith element is the total number of counts of the ith sample.
`ploidy`	The ploidy of the species. Cannot be `NULL` if `eps` is `NULL`.
`eps`	To estimate the sequencing erorr, we will only use points such that `ncounts / ssize >= eps`. If `ploidy` is specified and `eps = NULL`, then `eps` will be chosen by a heuristic.
