Pre-calculated `--pve` rounded down to 0.0

[YStrauchP4]

Hi!

I'm unable to pass my precalculated phenotype variant estimates:

> pwcoco-master/build/pwcoco \
    --bfile plinkout \
    --sum_stats1 exposure \
    --sum_stats2 outcome \
    --pve1 0.5 \
    --pve2 0.4 \
    --out output \
    --log log \
    --verbose

I also tried passing them as a string (--pve1 "0.5" for example), again no luck. The implementation seems to round it down to the next integer, as 1.4 is rounded to 1.0
