Add ultra-scroll

[Stebalien]

Brief summary of what the package does

ultra-scroll provides significantly improved smooth scrolling over the built-in pixel-scroll-precision-mode. It can also hide the cursor, disable hl-line, etc. when scrolling. Unfortunately, the "hide cursor" feature doesn't work with Evil because Evil constantly resets the cursor depending on the current state.

This integration hides the cursors for both motion and normal state when scrolling with ultra-scroll.
