Change Pecan/Bety load.bety.sh script to break apart ingest files beyond a certain size

[Chris-Schnaufer]

The load.bety.sh file loads large files in one bite, which can tie up database resources for a long time. Change the script to break apart large files and ingest them in pieces

[Chris-Schnaufer]

Waiting on weekend run (11/12/22) to confirm changes

Follow up: this worked, will put in a pull request onto Bety repo PecanProject/bety#740
