* What you can do:
* - add simple, unformated text
* - add formatted text
* Note: you can chain formatting codes but the color must be used first:
* e.g. BLACK + ITALIC will create black, italic text but ITALIC + BLACK will only create black text.
* - add animated text
* - chain multiple static and/or animated text together using chain()
* (Although chaining only static text together is pointless, text() is already able to to that)
* - add multiple lines by using NEW_LINE (either as String or as Supplier<String>)
* Note: formatting only applies for one line
* Note: having a NEW_LINE in animated text results in "skipping" of one formatting since NEW_LINE
* counts as character but is not displayed
*
* Note: adding a tooltip to an item multiple times also creates multiple lines (in the same order they were added)
*
* What you cannot do:
* - add a tooltip depending on NBT, tooltips are only mapped to name and meta
*
* This method is executed on postInit
