Promote cache when scanning
...
When scanning over a leveled store with a helper (e.g. segment filter and last modified date range), applying the filter will speed up the query when the block index cache is available to get_slots.
If it is not available, previously the leveled_sst did not then promote the cache after it had accessed the underlying blocks.
Now the code does this, and also when the cache has all been added, it extracts the largest last modified date so that sst files older than the passed in date can be immediately dismissed

Allow for caching of compaction scores
...
Potentially reduce the overheads of scoring each file on every run.
The change also alters the default thresholds for compaction to favour longer runs (which will tend towards greater storage efficiency).

Add ability to control journal size by object count
...
This helps when there are files wiht large numbers of key deltas (and hence small values), where otherwise the object count may get out of control.
