Korad KAxxxxP series support

We're happy to announce that libsigrok now supports the Korad KAxxxxP series of programmable power supplies, including the popular Korad KA3005P.

These are all 1-channel lab power supplies with various different max. voltage and current properties.

Velleman also resells them under the name PS3005D and LABPS3005D, as does Farnell/Tenma using their usual model names of 72-xxxx. See the Korad KAxxxxP series wiki page for details. If you know of other vendors who resell these devices, please let us know.

The protocol used by the power supplies is documented on our wiki page, together with various quirks and bugs in the device firmware and/or vendor documentation.

If you own a not-yet-supported device from this series, you can easily add support by telling the libsigrok driver about the "ID" that the power supply returns upon the "*IDN?" command, e.g. like this. Please send us a patch if you do so!

The driver was contributed by Hannu Vuolasaho, thanks a lot!
