Added long overdue credits because without them i would still struggle to understand the GPU. 

A few small changes. Nothing important.

## Known issues
This section is reserved for a listing of known issues. At present only this remains:
* Drops a single frame roughly every 5 seconds. This is due to different refresh rates of the LCDs and the builtin GBA hardware.
* Leaving GBA sleep mode or pressing HOME can cause persistent glitches (double scanlines/shifted picture).
* No scaling for now. This requires the GPU due to timing constraints.
* Save type hardcoded to 32 KiB (256k) SRAM for now.
* Save type hardcoded to 32 KiB (256k) SRAM. Unknown how save type detection will be done.
If you happen to stumble over another bug, please open an issue in the [official open_agb_firm repo on GitHub](https://github.com/profi200/open_agb_firm/issues) or contact me via other platforms.
