PS2 Floating-point: reconstructing console arithmetic behavior

PS2 Floating-point reconstructs aspects of PlayStation 2 floating-point behavior in Rust using console experiments as a baseline. Its Ps2Float type represents the console's floating-point variant and implements addition and subtraction, with test cases for ordinary values and special cases.
