Move the emulator into crates/gba-core, the original demo programs into crates/gba-demos, and the minifb frontend into crates/desktop. The binary is now gameboy-rust. Imports change from gba_rust to gba_core/gba_demos; no behavior changes. gba-core has no dependencies. Its integration tests use gba-demos as a development dependency.
