Size limit for detailed diff in `datacmp`?

[disinvite]

105 has a singleton variable with this member:

BurgerKingBurger_0xC field_3C_rec_buff[40000];

datacmp dutifully constructs the format string and list of offsets for this huge array of structs. As you might expect, this takes a while. To add insult to injury, the variable is uninitialized, so there isn't a pressing need to actually compare anything.

Is it reasonable to put a size limit on variables, beyond which we only compare raw data? If I do this, it significantly speeds up the datacmp run for this repo.
