**Full Changelog**: https://github.com/Amulet-Team/Amulet-NBT/compare/1.1...1.1.1

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.

This release massively updates the python library.
It splits it into more easy to use modules.
It modifies the behaviour a bit to behave more like the cython library.
It fixes some issues with the pickle library.

The cython library should get an update at some point so that the two behave the same.

It also fixes some install issues. Previously `cython` was installed when installing from the wheel despite not being needed and `wheel` was not installed when it was required when building from source.
