replace various comparison operators with spaceship-operator

[annihilatorq]

i decided to use auto operator<=>(const address&) const = default; instead of adding the <=> operator through the MATH_OPERATOR macro to ensure automatic generation of the == and != operators. when specifying a particular return type like std::strong_ordering in the macro, compiler doesn't automatically generate == and != due to the separation of comparison categories in cpp20. using auto with default allows the compiler to deduce the return type and generate all necessary comparison operators, which increases code simplicity and reduces redundancy

Ah yes, neat idea and looks good overall, tyty
I guess we don't need these macros anymore. Also not sure whether we have tests for operators or not. Will update your PR with these changes in a sec

Will merge once CI is green
