PeakTech 2170 support

Another new device was recently added to the list of libsigrok-supported hardware: PeakTech 2170.

This is a 20000 counts handheld LCR meter with USB connectivity.

It's using a standard Prolific PL2303 IC for communication with the host, and the Cyrustek ES51919/ES51920 chipset for the actual measurements.

You can find the usual set of teardown photos over in the sigrok wiki.

The device support was added to the existing (now more generic) driver for ES51919-based devices by Gerhard Sittig, thanks a lot!
