74cb5bab13 Fixed wrong brackets: size*count + pad can overflow before the cast 
=> Should fix #76 (most of the work has been done by Robin Mills in
   6e3855aed7)

The problem with #76 is the contents of the 26th IFD, with the
following contents:
tag: 0x8649
type: 0x1
count: 0xffff ffff
offset: 0x4974

The issue is the size of count (uint32_t), as adding anything to it
causes an overflow. Especially the expression:
(size*count + pad+20)
results in an overflow and gives 20 as a result instead of
0x100000014, thus the condition in the if in the next line is false
and the program continues to run (until it crashes at io.read).

To properly account for the overflow, the brackets have to be removed,
as then the result is saved in the correctly sized type and not cast
after being calculated in the smaller type.

The brackets have also been removed from bigtiffimage.cpp, where the
same issue is present.
