Support 04f3:0c77 Elan Microelectronics Corp. ELAN:ARM-M4

I would like to report that my fingerprint scanner 04f3:0c77 (which is found in the Asus Expertbook B7 Flip) works with your proof of concept code, as long as I set ID_PRODUCT = 0x0c77.

It is quite finicky, and I don't know if it's working at it best, but it could certainly enroll two different fingers and later verify them as the correct finger, though often after a couple of tries.

Hi, I haven't really been working on the driver lately. If you're able to test and apply fixes to the code over there in libfprint feel free to join the conversation.

Hello, I am working on a proof of concept that does support the 04f3:0c80. And may also support the 0c77 variant. I will release the proof of concept to my github soon.

I know that Surface Laptop folks are waiting for 04f3:0c5a and 04f3:0c80 (SLG1 and SLG2 respectively). I don't know how these things work at all, but I'm looking forward to this thread.
