Expose C API

[falseywinchnet]

I'm interested in porting my driver to use nusb as a backend over libusb.
libusb has had some flaky issues and is gpl, and my work is MIT licensed, so this alteration if possible is of interest to me. Are you considering including a means to invoke into nusb from c/c++ code? I am considering Zngur might work but I am hesitant to get an llm to hallucinate a crappy wrapper

nusb is the only new option in this space so seeing it is very cool!

It's not something I plan to work on, but it would be great if someone wants to do it.
