Backtraces (#590)
Implements a very basic backtrace and the ability to format them

If you run the panic example and press A, you get:

```
[ERROR] GBA Debug: [failed]
[ERROR] GBA Debug: debug data: ce3-1ee7-1fb7-24d-1ad
[FATAL] GBA Debug: Error: panicked at src/memory_mapped.rs:101:24:
index out of bounds: the len is 240 but the index is 240
```

which you can then prettify with:

```
> agb-addr2line ../target/thumbv4t-none-eabi/debug/examples/panic 0ce3-1f57-2027-024d-01ad
