Integer overflow in stack walker when processing minidump.

Apologies for the very poorly minimised test case, just making a note of this now so I don't forget.

The bug is in the stack walker, but I found this when fuzzing `minidump_processor`.

```
thread 'test_stack_walk_overflow' panicked at 'attempt to add with overflow', /home/jess/src/rust-minidump/minidump-processor/src/stackwalker/x86.rs:165:21
```

it's like 300 lines long, i hid it here
