Make a few improvements to the SioSerial struct: - Have init() return Self. It's more ergonomic to create and initialize the empty struct in one call. - Enable FIFO. The GBA has a 4-byte UART FIFO. This makes it less likely to lose received bytes. - Derive Clone on SioSerial so it can be split and shared with an interrupt. - Derive Debug on SioError so results can be unwrapped.
