cron log getting very large

output from the cronjob to search for bams appends to a log file, doesn't look to be on a timed rotation backup so just gets indefinitely bigger: https://github.com/eastgenomics/Genetics_Ark/blob/10a9d9bd3c1adc132ae44a5e16760fcdb7ce8204/cron/crontab#L3

should either switch to proper logging in the script and remove the redirect in the crontab, or add something like this: https://github.com/eastgenomics/dx-streaming-upload/blob/476b28af980ad62c5f2750cc0b6920b82a287b11/cron/crontab#L4
