Double free in algorithmica

An issue was discovered in the algorithmica crate through 2021-03-07 for Rust. In the affected versions of this crate, merge_sort::merge() wildly duplicates and drops ownership of T without guarding against double-free. Due to such implementation, simply invoking merge_sort::merge() on Vec<T: Drop> can cause double free bugs.
