Anchor Aura rewrite

[Gingerbeard5773]

Type of change

• [ ] Bug fix
• [x] New feature

Description

• Completely overhauls Anchor Aura, with massive improvements.

This new anchor aura is similar to Crystal Aura in functionality- it finds the most optimal area around the target by using the blockiterator. Previously it would choose from a list of pre-set offsets, which was very shoddy.

New settings have been added so that the Anchor Aura can be configured depending on the server's level of anti-cheat.

• Air Place If the server doesn't allow air placement, it can be turned off.
• Walls Range Allows for raycasting to affect where anchors can be placed/broken.
• Place Automatic placement can be turned off so that the anchor aura is used only to break any anchors you place manually.

Drafted as I need to add in proper configurable delays between placing the anchor -> inputting glowstone -> breaking the anchor. ATM inputting glowstone and breaking the anchor is attempted on the same tick, which can flag anti-cheats and cause the player to be disconnected.
