Add automatic read/write items for all pocket items (1-40) (#51)

Decentralizes pocket injection logic from SysBotUI so that other auto-injectors can be passed in (future? like terrain/overworld items).

Adds validation to not modify items if the pocket data doesn't have the expected layout.

Closes #47 by implementing things in a more abstract & extendable way. Thanks @jfmherokiller for the example implementation which served as an inspiration!
