Not an issue but a suggestion, Adding opencl or cuda support

Hi, I have used the bip38 library for one of my projects, ccrecover node and i am very appricative of the work you all have put in to make the python library. I was mainly looking at seeing if by any chance if there could be some support for gpu decryption. It is a bit of a stretch to ask. If not I was wondering if you had the reasources for how you developed the library as I would be interested in adding some gpu support to it
