`./pcm-pcie 0.5 -csv=test.log` runs >100x faster | integers go half speed

Running pcm-pcie with delays below 1-second returns hundreds of entries per second.

# time ./pcm-pcie 0.5 -csv=test.log -i=1000
...
real    0m3.010s
user    0m0.275s
sys     0m2.596s

1000 x 0.5 != 3

pcm-core, pcm-iio, pcm-latency, pcm-memory, pcm-numa, and pcm-power all appear to function properly.

Additionally, whole numbers appear to be doubled:

# time ./pcm/build/bin/pcm-pcie 1 -csv=test.log -i=10
...
real    0m20.489s
user    0m0.293s 
sys     0m0.423s 

# time ./pcm/build/bin/pcm-pcie 2 -csv=test.log -i=10
...
real    0m40.480s
user    0m0.290s 
sys     0m0.563s
