* Integrates num_traits more closely.
* Implements signed for our num, and the vector2d / rect abs now can use
our fixnum.
* This is potentially breaking.
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:
```

GitHub pages, for whatever reason, doesn't compress the combo ROM and
instead serves it uncompressed. Therefore, we explicitly compress it
using the highest compression level at build time and explicitly
decompress it.
Previously we would download 14.69MB, now we download 7.84MB.
Approximately 50% savings.
* We want to always use animation frames as our time to call the main
loop because otherwise the timing is inconsistent leading to very bad
audio.
* We don't want to call the main loop every frame otherwise > 60hz
screens will play too fast.
* We can't emscripten's frameskipping becuase it only allows for
integers whereas screeens come in many other framerates such as 75hz,
90hz, 144hz, etc.
* Therefore we manually manage frameskipping by ~~ab~~using pause and
resume game which internally just enable and disable the emscripten's
calling of the main loop. (see
27dede256b/src/platform/wasm/main.c (L183)).
* We could modify the code to let us call the main loop ourselves and
take full control over this, but for now this is okay.
* Controls were broken on mobile because dpad movement was interpreted
as a/b button presses.
* Fixes it to:
* Handle multiple fingers using the dpad / a / b buttons
* A dpad movement must start on the dpad, and a/b presses must start on
a/b.
