"DLL Load Failed" On Windows 7 With Python 3.8,
because some of DLLs try to import "bcryptprimitives" function, which doesn't exist on Windows 7.

This is bcryptprimitives.dll export on Windows 7:

This is _rust.pyd 42.0.6 import:

This is _rust.pyd 42.0.5 import:

ProcessPrng function in bcryptprimitives, only exist in Windows 10 above.

If you want to keep 42.0.6 using bcryptprimitives on Windows,
you should remove support for Python 3.8 below.

Because Python 3.8 below still support Windows 7.
