Contributions summary:Mariusz's contributions primarily focused on refactoring the internal logic of the memoizee library. This involved renaming options, reworking garbage collection (GC) mode, and improving the internal handling of asynchronous functions. They made several code adjustments across multiple files, primarily in the `lib` and `test` directories. Additionally, they added and enhanced testing around different memoization modes (e.g., max-age, refCounter, and general memoization).
