Feature Request: Enhanced SupportHelper option to add checksum (SHA256) validation for Script execution.

[headmin]

Hi @jordywitteman,

As discussed earlier this week at the Univ of Utah - MacAdmin meeting where we both presented, it would be great to have an additional option on the SupportHelper to only run from a list of file hashes that are allowed to run, as a measure to secure and gate when to execute privileged scripts.

This idea is already present in another great community project (hats off to @bartreardon) - so the purpose is very well explained on File Verification in the Outset wiki here, as is the approach (see here Checksum.swift).
