Create a new NBTParser class for snbt & path lookup

[TheMode]

Deprecate SNBTParser in favor of a new NBTParser class hosting various static utils

NBT parseSnbt(String snbt)

NBT extractPath(NBTCompound compound, String path)

String extractPath(String compoundSnbt, String path)

NBTCompound replacePath(NBTCompound compound, String path, NBT nbt)

String replacePath(String compoundSnbt, String path, NBT nbt)

The new path system is suggested to become a perfect copy of sqlite's json path syntax: https://www.sqlite.org/json1.html#jex
