Add three Structure Block related settings (#664)

* Added structureBlockOutlineDistance

* Added structureBlockIgnored

* Added structureBlockLimit

* Made structureBlockLimit work on dedicated server

* Correct packet contents check and fix mixin list

* Add limits to structure block settings, slight optimisation to ignored block

* Fixed the `structureBlockLimit` limit

* Update src/main/java/carpet/CarpetSettings.java
