added version 2.3.4 with more control over dsk and transition styles

added new `/atem/transition/set-style` calls
added new `/atem/dsk` calls

Note that I don't actually like how the `/atem/dsk` calls are laid out currently, but I didn't want to change the existing `/atem/dsk/1` calls in case you were using them. Feel free to clean up those addresses.
