Add support for the Wingtech CT2MHS01 hotspot, a Qualcomm mdm9650-based
device with a screen available for US$15-35. This device is often used
as a base platform for while labeled versions like the T-Mobile TMOHS1.
AT&T branded versions of the hotspot seem to be the most abundant.
The device has a framebuffer-driven screen at /dev/fb0 that behaves
similarly to the Orbic RC400L, although the userspace program
`displaygui` refreshes the screen significantly more often than on the
Orbic. This causes the green line on the screen to subtly flicker and
only be displayed during some frames. Subsequent work to fully control
the display without removing the OEM interface is desired.
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.

Mixing async and sync I/O leads to a multitude of complications, and
generally speaking it's much more convenient to stick to one paradigm
or the other. Since axum (and many other HTTP servers) use async,
and since async is a convenient model for performing operations like
"handle an MPSC message or file read, whichever happens first", let's
commit to an async interface.
