Duckyscript 3 Commands not Working

[ToxicMonster]

Describe the issue
Duckyscript 3 commands are not working when added to payload.dd file including WAIT_FOR_BUTTON_PRESS, functions and variables

To Reproduce
Add one of the duckyscript 3 commands to payload

Expected behavior
Duckyscript 3 command executes as per Hak5 docs.

Additional context
Addition of duckyscript 3 commands would greatly increase functionality of pico as rubber ducky. Happy to help with addition if required as I would find much use for these functions but don't have the time to fully commit to development for PR.

I'll have some time in a couple of weeks to take a look at this issue.
