Compound-index sort acceleration
Previously, only single-field sorts were index-accelerated — multi-field sorts always fell back to a Python list sort after the fetch. v0.3.0a50 adds compound-index sort acceleration: a sort spec like {a: 1, b: -1} matches a compound index {a: 1, b: -1} (or its reverse) and the storage layer walks the B-tree in the right direction, skipping the post-sort step entirely. Mixed-direction compound indexes work too — each field's bytes are inverted at encode time when its direction is -1, so the WT B-tree gives the index's natural order with a forward walk.
