GHSA-G23H-7VF9-XC25 Mimalloc Can Allocate Memory with Bad Alignment

This crate depended on a promise regarding alignments made by the author of the mimalloc allocator to avoid using aligned allocation functions where possible for performance reasons. Since then, the mimalloc allocator's logic changed, making it break this promise. This caused this crate to return...
