Fix entry point sys.argv error
Fix entry point sys.argv error

When using LIVVkit programmatically from a python package that accepted
command line arguments, LIVVkit ignores the arguments passed to main in
favor of the calling packages command line arguments.

Now, LIVVkit only uses the available command line arguments if no
arguments were passed to main.
