Fix 'Unable to find method createTag' on 1.15 servers (#2642)

* Fix 'Unable to find method createTag' on 1.15 servers (#2629)

Mojang apparently refactored their NBT code in 1.15, so the NBT
parsing code in NbtFactory that used Mojang's NBT code via Reflection
broke. Since PlotSquared now depends on WorldEdit, it is much easier
to use their NBT parsing library than to update the Reflection-based
code.

* Clean up NBT streams properly
