Fix MLO Instance Data

[kirill-mapper]

Fixing MLO Instance Data - groupId, floorId, defaultEntitySets*, numExitPortals, MLOInstflags.
*There is a bug with defaultEntitySets - it is not possible to get and set data items, for example in vanilla files v_metro_interior_metro_station_3_seoul_milo__3.ymap, probably incorrect offset, parsing, etc, we get null:

CodeWalker/CodeWalker.Core/GameFiles/FileTypes/YmapFile.cs

Line 301 in c45ea83

uint[] defentsets = MetaTypes.GetUintArray(Meta, CMloInstanceDefs[i].defaultEntitySets);

mloi could be null

I couldn't figure out how to solve this. I wanted to suggest that probably getting zero instead of data is a problem from the end. I also didn't find a version of CW where the logic you conceived with defaultEntitySets would work. Now CW can't get an array of vanilla data defaultEntitySets, but it can set data, but probably in a different place. When reading again, the data will be read from a different place.

@dexyfex GetUintArray returns null due to StructureNameHash mismatch (expected 21/UINT, got 74) in the data block. v_metro_interior_metro_station_3_seoul_milo__3.ymap

So, I fixed defaultEntitySets, now it works.
I also noticed that CMloInstanceDefs[i].defaultEntitySets.PointerDataIndex changes after resaving, the input was 3, after 1, is this how it should be?
