Support for delays > 256

Even if it just internally splits into multiple delays 68k-side, it's one less API gotcha

For the record, that's an issue with esf.68k (which outputs events directly), every other tool does split them.

I was gonna add a loop, then remembered I can't modify macro arguments. I may have to use a rept with an expression instead, although that'd break compatibility with asmx (which doesn't support it and I haven't implemented it either) :/ Alternative is to create a waste variable to use as counter (but that means making assumptions about the surrounding labels, since it can break scope for local labels). Gotta see.
