feat(engine): free and multi zones data storage improvements

[ultraviolet-jordan]

Instead of storing per tile in the sets, store it per zone index.
This decreases the amount stored within them (it's basically original length/64).

423616 (free) --> 6619 (free)
186816 (multi) --> 2919 (multi)

This improves the server startup time about 2 seconds on my pc (1 second startup time).
According to console, this saves about 20mb of memory but idk...
I kept all comments in the csv file in the proper spots.

Looks good. I think they converted multicb zones to use areas after 06 which would have then allowed them to go tile by tile

I think they're supposed to be individually marked in jm2 files with the other map info, but we can worry about that later i think

That area marked in yellow probably doesn't belong to our version's multicombat area because as shown in the picture, the top 8x8 square doesn't have multicombat.
and I don't see any significant reason why it would in the lower squares either.
the picture is from the 2005 Easter event.

Probably added when jagex updated the region area 47_51 in connection with farming and the graphics updated the area at the same time.
because the multicombat symbol appears in the materials after the graphics update.

I have removed those 3 for now then unless someone says otherwise:
