Randomly sample sites from an input VCF file. Scale the sampling probability by the field specified by --scale-by (see advanced controls).  This may be
used to provide uniform sampling across allele frequencies, for instance (AF field in this case).

Options::

    -r, --rate RATE      base sampling probability per locus
    -s, --scale-by KEY   scale sampling likelihood by this Float info field
    -p, --random-seed N  use this random seed
