December 2024 monthly summary for lambdaclass/cairo-vm: Delivered a major enhancement to the relocation system by refactoring the relocation table to a HashMap<usize, MaybeRelocatable>, enabling more flexible and scalable addressing. Implemented feature-driven compilation controlled by the extensive_hints flag to support different destination pointer types. Updated documentation and added new tests to ensure the correctness of the modified relocation logic. This work is associated with commit 4e55e354479a835341b0bdcadd340cf71da576b7, titled "Convert relocation table to HashMap<usize, MaybeRelocatable> (#1862)".
