Allow multi file granules

Question: What needs to be in the UMM-G size? (Amy)

Example data set?

We could check how this is currently handled in existing UMM-G

Type in CNM message might have to change

Specific questions for @afitzgerrell blocking this ticket: What is the file size that needs to go into the UMM-G for multi science file granules?

[afitzgerrell]

The file size reported in UMM-G (SizeInBytes) would be the sum of all the data files comprising the multi-file granule (i.e., everything packaged in a granule that is not the external, file-level umm-g metadata file, browse image, or ancillary files like QA and/or PH files). I don't recall ever receiving QA and PH files with a data producer-delivered data set). There's an example of this here in the UMM-G documentation, but I've attached a visual here in case helpful.

To state this another way as: the umm-g SizeInBytes should be the sum of all the files in a product where the files are defined as "type": "data" in the CNM.
