Hollow Knight June 2022 Updates (#720)

This is a combined PR for assorted Hollow Knight updates for June 2022 that have cleared testing. It supersedes any HK-exclusive PRs open by myself or @Alchav unless stated otherwise.

Summary of changes below:

 * Implement Split Claw, Split Cloak, Split Superdash, Randomize Nail, Randomize Focus, Randomize Swim and Elevator 
 * Pass options (@Alchav)
 * Add support for Deathlink with three different modes (@dewiniaid)
 * Add customizable additional shop slots per-shop (@Alchav) and overall (@dewiniaid)
 * Overhaul shop cost output to be more generic and account for all locations with standard costs (such as Stag Stations, Cornifer, and Divine) (@dewiniaid)
 * Add "CostSanity", allowing random prices using any cost type to be chosen for any location with a cost. (e.g. a Stag station requiring 15 grubs to obtain an item)
 * Item classification fixes (Map and Journal items are fillter, Mask Shards/Pale Ore/Vessel Fragments are useful) (@Alchav)
 * Fix Ijii -> Jiji (@Alchav )
 * General code quality updates

The above changes are only for the HK world.
