When can b.maxSz be 0? It should always have a valid value.

I've kept the zero value as an "unbounded" buffer. The earlier API set maxSz = math.MaxInt32 (roughly 2.1GB) by default. The caller is expected to set this using the WithMaxSize API now. Should I change it back?

z.Treeshould use az.Bufferbacking.z.Buffershould use az.MmapFilebacking.z.Buffer, so it doesn't delete the file after closing.z.Tree, so that we can use it for persistent storage.This change is
