// locality against optimal space usage.
// How To Use:
// 1. Create a DqnMemStack struct and pass it into an initialisation function
// - InitWithFixedMem() allows you to pass in your own memory which is
// converted to a memory block. This disables dynamic allocation.
// NOTE: Space is reserved in the given memory for MemStackBlock metadata.
// - InitWithFixedSize() allows you to to disable dynamic allocations and
// sub-allocate from the initial MemStack allocation size only.
// 2. Use DqnMemStack_Push(..) to allocate memory for use.
// - "Freeing" memory is dealt by creating temporary MemStacks or using the
// BeginTempRegion and EndTempRegion functions. Specifically freeing
// individual items is typically not generalisable in this scheme.
// DqnMemStack stack = {};
// stack.Init(DQN_MEGABYTE(1), true, DqnMemStack::Flag::BoundsGuard);
// u8 *data = stack.Push(128);
