Is it possible to use the heap allocator on a memory region that I provide during runtime? Typically Nim would use the OS allocator (mmap, VirtualAlloc) to grab memory pages for its allocator, but what if I have a fixed memory region that I'd like to use as a heap, is there a way to _[attach](https://forum.nim-lang.org/postActivity.xml#attach) the allocator to such an area at runtime?
