Add build features for multiple device types

The bin crate now has two features, one for each supported device.

* The IOCTL change from #142 is compiled in conditionally.
* Tp-link display is supported & tested for HW rev 3 and HW rev 5.

The release tarballs now contain two rayhunter-daemon binaries, for
orbic and tplink. An installer for tplink is not yet included.
