Glasgow Embedded / Glasgow - History

cli: Modify "glasgow factory ..." command to use FX2BootloaderDevice

This serves to make it use the support.usb abstraction.

hardware.device: Add FX2BootloaderDevice

FX2BootloaderDevice is very similar to FX2Device from libfx2. The primary
differences are:
a) parameters in FX2Device such as page size, and address width are fixed
to the ones matching the Glasgow hardware/firmware
b) USB requsts use the USB abstraction from support

CI: push latest wheel to https://glasgow-embedded.org/.

This will be used by the WebUSB port.

applet.interface.uart: change quit sequence to `~` then `.`.

This sequence is similar to SSH, except it doesn't have to follow
a newline. It's changed because on some non-US keyboard layouts it
may be difficult to enter Ctrl+\ (issue #998), and because it was
training users to use Ctrl+\ to quit other applets or modes, which
sends SIGQUIT and dumps core on some OSes (issue #568).

Fixes #998.
