@ammedd and I discussed previously that it would be good to increase the random noise applied to the drifter particle seeding locations to allow them to spread apart a bit more when multiple drifters are released from the same waypoint. Therefore, this PR arbitrarily increases the amount of offset via _random_noise in utils.py.

To see the effect, I have copied two images below showing drifter deployments (5 drifters per waypoints, 42 day lifetimes). 1) with the old offset and 2) with the new offset. I think it looks better now...

1) Old

2) New
