midx: teach `nth_midxed_offset()` about incremental MIDXs
In a similar fashion as in previous commits, teach the function `nth_midxed_offset()` about incremental MIDXs. The given object `pos` is used to find the containing MIDX, and translated back into a MIDX-local position by assigning the return value of `midx_for_object()` to it.
