       A memory resource that allocates from a fixed-size buffer.

       The main feature of a pmr::monotonic_buffer_resource is that its do_deallocate does nothing. This makes
       it very fast because there is no need to manage a free list, and every allocation simply returns a new
       block of memory, rather than searching for a suitably-sized free block. Because deallocating is a no-op,
       the amount of memory used by the resource only grows until release() (or the destructor) is called to
       return all memory to upstream.

       A monotonic_buffer_resource can be initialized with a buffer that will be used to satisfy all allocation
       requests, until the buffer is full. After that a new buffer will be allocated from the upstream resource.
       By using a stack buffer and pmr::null_memory_resource() as the upstream you can get a memory resource
       that only uses the stack and never dynamically allocates.
