++ Added some Exceptions to places missing errors temporarily (Will Change them to be custom exceptions)
~ Optimized Some Code to Take advantage of newer Language Features accessible in .Net Standard 2.1
~ UpdateWorkbook() Now Has an Optional Bool parameter Called Update Which replaces the update variable that was inside of it to allow for the optional to call into the if statement that was using it, since for some reason it was never possible before.
