Removed old chunk map.
Removed flush(Region) function as it's a bit trickier to implement with the new hash table, and it's not clear that we need it.

Added a second PagedVolume to the tests with much higher allowed memory usage. This makes more sense when testing random access, as low permitted memory usage causes disk IO to become the bottleneck.

Commented out optimized path in sampler as it doesn't work now that we are using Morton ordering for the data in chunks. However, we can probably reinstate such a fast path if we give some thought as to how it should be done.
