Added prepare script to update cli hardcoded version number

[GarthDB]

Description

It's tricky to read in the package json file version number for the cli to return for tdiff --version. I added a prepare script to the package json that will find and replace the hardcoded version number in the src/lib/cli.js file.

How Has This Been Tested?

Locally only. We won't be able to know if it's working for sure without publishing the package.
