Describe the requested feature

For some raw_records with decompressed chunk size awkward, they might raise memory exceed error by chance, like run 050775.

To reproduce, set peaklets_memory in XENON_CONFIG as 14500 (MB):

python3 /home/xudc/outsource/outsource/scripts/submit.py --context xenonnt_offline --xedocs_version global_v16 --image el9.2024.09.1 --run 50775 --local_transfer --ignore_processed

But if you set memory to 16000, there will be no error.

According to @FaroutYLq , when setting the memory requirement to below 15GB we can use more nodes. So this chunk size is awkward.
