    @subTee's reflexive loader
    Required Dependencies: msbuild, csc
    Execute Run-UpdateKatz
    This will download the latest mimikatz source and a reflexive PE loader, unzip, compile,
    Execute: Run-UpdateKatz -Verbose
    This will download the latest mimikatz source and @subTee's reflexive PE loader, unzip, compile,
    encrypt, and package the mimikatz binary into Procmon64.exe. The file itself will bypass AV.
    Running will likely get picked up by Sysmon and possible be killed by AV. Note that
    the user credentials torbot are hardcoded since they have access to github.
    Running is a different story.
    Obviously run this from a clean machine, disable AV so you don't lose mimikatz
