Current quest file format is not git-friendly

[KatatsumuriPan]

Removing quest causes the commit to become too large.
This is an example.

To fix it, I suggest using NBTTagCompound keyed by questID instead of NBTTagList.
This changes the format of the quest file(DefaultQuests.json) and breaks forward compatibility.

Additionally, I don't think BQ's unique file format is human-friendly.
I recommend using Key-Sorted-SNBT.(original SNBT keys are randomly sorted...)

Furthermore, splitting quest files like gtnh is better.
