[Beta Testing with SPs] Write storage script

[davidd8]

Write a test script for SPs that stores ~100GB to Motion to then be stored on the SP via a storage deal on Filecoin. May need to track important CIDs of the data to retrieve later on.

Assume this script will be used multiple times for each SP onboarded to Motion.
