Handle missing RDPS data

[dgboss]

We run an hourly cron job and often run into a situation where our cron job kicks off and starts downloading RDPS precip gribs before the ECCC has finished uploading them. When this happens we don't have the data we need to subtract precip rasters. This is expected behaviour and we now simply exit and pick things up during the next cron job when ECCC has finished uploading the precip gribs.
