I don"t know if this is more efficient or not, but it looks cleaner. Define `_DEBUG_MANCALC_OFFSETS` to use the previous offset calculation code.

Add TODO() for unimplemented functions
Add unimplemented function prototype `v_in(v,r1,r2)`. If comparing versions via range is needed in the future, we can implement this. It is trivially implemented to comparing bswap"d raws (big endian comparisons), so we could make an endian-aware raw comparison for this, or we could compare components. Too much boilerplate for now, and i don"t think such a function would be useful, so leaving it dead.
