[fprint] upeksonly device support: 147e:1001 Upek

[Reuben Martin]

I recently bought a laptop from system76. In the process of installing
Gentoo and getting all the devices working I noticed that the finger
swipe sensor device 147e:1001 is very similar to the already supported
147e:1000. I assume it's just a newer version of the same product. I
hacked it's vendor & product ids as well as its bcdDevice into
libfprint to be treated the same as the older model. fprintd-enroll is
able to access the device, but apparently it's different enough that
the sensor data isn't recognized. It's doesn't seem to be aware that
anything has been swiped on the sensor.

Can I provide any info that would help get the device supported?
