v1.16.0

This release makes it possible for firmware updates to request larger block
cache sizes. Earlier versions fixed the cache at 8 MB which is too small for
many delta firmware update use cases. The visible effect is that delta firmware
updates become extremely slow (sometimes >1 hour) due to thrashing when their
source window is set to values much larger than 8 MB.
