Typo in vcf.h

[yuw444]

Below are my understandings:

1. bcf_gt_phased and bcf_gt_unphased encode idx to val
2. bcf_gt_is_phased and bcf_gt_allele decode val to phase info and idx

For instance, idx = 0(ref), 1, 2, 3(alt)

when phased(|), the corresponding values are
val = 3, 5, 7, 9;

when unphased (\), the corresponding values are
val = 2, 4, 6, 8;

According to vcf: line 1168, I believe val is what the author refers to.

That's correct. Thank you
