MetaData.SaveTypeHash defines the end of the hash table for simple data and the start
of complex data (arrays, etc)
in official TOTK savegames, its at 0x03c800 (or before, if v1.0)
but we cannot rely on that offset because of game mods or even future game versions,
which might push it further if they add new variables to the game
so, in order to make the editor compatible with both official game and mods, we ensure
we will always find the exact offset for MetaData.SaveTypeHash
this offset is just used when looking for a variable in the savegame, because we only
need to search up to that offset
