In dcgerard/updogAlpha: Using Parental Data for Offspring Genotyping

Just a reparameterization of obj_offspring.

1 2	obj_offspring_reparam(ocounts, osize, ploidy, prob_geno, s, ell, r, outlier = FALSE, out_prop = 0.01)

`ocounts`	The observed counts of the refernce allele for each individual.
`osize`	The observed number of reads for each individuals.
`ploidy`	An integer. The ploidy of the species. This is assumed to be the same for each individual.
`prob_geno`	The allele frequencies of the genotypes. See `get_prob_geno`.
`s`	Same as `log(bias_val)` in `obj_offspring`.
`ell`	We have `seq_error = expit(ell)` from `obj_offspring`.
`r`	Same as `log((1.0 - od_param) / od_param)` from `obj_offspring`.
`outlier`	A logical. Should we include an outlier model (`TRUE`) or not (`FALSE`)? Defaults to `FALSE`.
`out_prop`	The proportion of points that are outliers. Defaults (quite arbitrarily) to `0.01`.
