RES doesn't count up cog PC in listings

I checked, this was already there before fixing #462

This is for DAT code in Spin files only, PASM-only seems fine.

I know what's happening here -- COG addresses are not passed through in the debug info used to generate the listing for inline asm. There's a hack to find ORG addresses, but that only works for literal integers. We could use a similar hack for RES (allowing this example to work) but it would fail if a symbolic constant like res N were used. I think a better option is to re-work the debug info to include COG PC's, but that will take a while.

Yeah, putting COG PC's into debug info is much harder than I thought :(. For now the hack is in place so in common cases we will get sensible PCs in the listing.
