Read a Format 5 SNP using a persistent open connection

Description

Like getbd5snp_buf but reuses an already-open file connection instead of opening and closing it on every call. Use openbd5con before the loop and closebd5con (or let the finalizer handle it) after.

Arguments

bd5info	Object returned by getbdinfo.
snp	1-based integer index or character SNP ID.

p0	Pre-allocated numeric(n_samples) vector.
p1	Pre-allocated numeric(n_samples) vector.
p2	Pre-allocated numeric(n_samples) vector.
bd5con	Object returned by openbd5con.

Value

NULL invisibly. dosage, p0, p1, and p2 are updated in place.
