This release removes the python version of the NBT library and massively rewrites the cython library.

This should be backwards compatible with the old version but some features are depreciated and renamed.
NBTFile has been depreciated and replaced with named versions of the tags. `NamedCompound` for example.
These behave like the old NBTFile but the value can only have one type. This was done because the type in the NBTFile was ambiguous.
The NBTFile used to have a `value` attribute. This has been renamed to `tag` in the named variants. `value` still exists but is depreciated.
The tags used to also have a `value` attribute. This has been renamed to `py_data` to be more clear. `value` still exists but is depreciated.

The new version should behave more like the python types. Some of the behaviour was missing in the old version.

Added hash support to the NBT classes so that they can be used as dictionary keys.
