Port buffer skip functionality by hand. IT WORKS!
All it need was absolute based buffering. This opens up per serial command pausing, clean resuming from anywhere, and lots more.

This still needs some work on wrapper functions and bufferSkip actions for commands other than “move”
Send the entire argument object, not just the parts we “care” about.
Ensure height runs before park.
This probably isn’t needed, but it seems like a good thing to do.
