Unicorn-fy

Added
- Since Unicorn-Fy is delivered as a compiled C extension, IDEs such as Pycharm and Visual Code cannot use information
about available methods, parameters and their types for autocomplete and other intellisense functions. As a solution,
from now on stub files (PYI) will be created in the build process and attached to the packages. The IDEs can
automatically obtain the required information from these.

Removed
- `binance_je_websocket()`
- `jex_com_websocket()`

unicorn-fy` can now also be installed on all architectures on which there are no precompiled packages from LUCIT. PIP
now automatically recognises whether there is a suitable precompiled package and if not, the source is automatically
compiled on the target system during the installation process with Cython. Even if you don't have to do anything
special, please note that this process takes some time!
